Cucullia asteroides - the Goldenrod Hooded Owlet moth

This very striking caterpillar appeared on an aster plant in our front yard late last August.  I wanted to see what he would become, so I placed him in a jar with aster clippings, some mulch on the bottom, and a couple sticks in case he needed them for pupation.

He was a very messy eater, clipping leaves off and letting them fall to the ground; I've read or heard that some caterpillars employ this strategy so that partially-eaten leaves on the plant do not give away their presence.  I do have to say this guy was well camouflaged, because there were times when I had difficulty locating him in the jar.

In mid-September he disappeared.  Totally.  I knew he had burrowed into the mulch at the bottom to pupate, so I placed the jar in our unheated garage for the winter.  A couple weeks ago he reappeared, as the rather inconspicuous moth shown here.

As best I can tell, he's one of the hundreds of species of Cucullia moths - Cucullia asteroides, as best I can tell.  Not a colorful creature by human standards (or by lepidopteran standards), but I suspect that drab coloration serves the defenseless adult well for camo, just as the striking green stripes served the caterpillar.

Can anyone identify these "sand tunnels?"

One of my favorite nature blogs - A Prairie Haven - has offered a puzzle to be solved.  The structures in the photo above were found on a farm in Wisconsin.
They're built up along the branches of small shrubs - mostly Sand Cherry.  They're close to the ground - none more than about 8 inches high.
The first thought was that they were termite tunnels, and they do resemble the connections that termites use to travel from their nests into above-ground structures.  These structures, however, are made of sand, and when they were examined by a termitologist, she noted that the sand grains were fused by webbing - not a feature of termite structures.  She postulates that these could be made by ants, but the puzzle is still under investigation.

Any myrmecologists out there who could confirm or clarify this?   You can post your comments at her blog, or here and I'll forward the information.

The answer is in the Comment thread - this is a construction made by the larva of a moth (Prionapteryx nebulifera).  The process was originally described in 1905 in the pine barrens of New Jersey.

Floor-to-ceiling bookcases

This image is one of several dozen compiled at Desire to Inspire in response to a reader request for ideas/images of floor-to-ceiling bookcases.

Our house has a few thousand books stored in a variety of bookcases in virtually every room.  But as I get older, the desire to keep every book that I enjoy has started to fade.  I want to have access to books (through libraries or online) and I want to keep certain reference books or hard-to-find books or books that I have extensively underlined.  But do I still need to keep my collection of 66 Agatha Christie mysteries scrounged from used book stores during a decade of searching?  All those John Dickson Carrs/Carter Dicksons that I want to reread "when I get old" - do I need to keep the books themselves?  I don't know.  But I do love seeing people's libraries/bookshelves when I visit homes of neighbors and friends.  They tell me a lot about what the people are like.

Here's a wonderful quote from Isaac Asimov:
There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."
That was quoted in Newsweek magazine in January of 1980.   The situation doesn't appear to have improved in the past 30 years.

Quote found at Reddit, where someone recommended a book from 1966 by Richard Hofstadter: "Anti-Intellectualism in American Life," the Amazon review of which offers this excerpt:
Unfortunately, America's practical culture has never embraced intellectuals. The intellectuals' education and expertise are viewed as a form of power or privilege. Intellectuals are seen as a small arrogant elite who are pretentious, conceited, snobbish. Geniuses' are described as eccentric, and their talents dismissed as mere cleverness. Their cultured view is seen as impractical, and their sophistication as ineffectual. Their emphasis on knowledge and education is viewed as subversive, and it threatens to produce social decadence.

Instead, the anti-intellectuals believe that the plain sense of the common man is altogether adequate and superior to formal knowledge and expertise from schools. The truths of the heart, experience, and old-fashioned principles of religion, character, instinct, and morality are more reliable guides to life than education. After all, we idolize the self-made man in America.

Hofstadter goes on to cite examples of anti-intellectualism from the nations founding to today. For example, the founding fathers were sages, scientists, and men of cultivation, yet the Federalists attacked the brilliant Thomas Jefferson by portraying the curiosity of his active mind as too trivial and ridiculous for important affairs...

Turning to education, Hofstadter points out that broad public education in the US was started not for developing the mind or the pride of learning for its own sake, but for its supposed political and economic benefits. Children were viewed not minds to be developed, but as citizens to be trained for a stable democracy.

Yet another Guantanamo detainee is released

What's most significant about this is that Hassen is now the 36th detainee who has won his habeas hearing since the Supreme Court in 2008 ruled they have the right to such hearings -- out of 50 whose petitions have been heard.  In other words, 72% of Guantanamo detainees who finally were able to obtain just minimal due process (which is what a habeas hearing is) -- after years of being in a cage without charges -- have been found by federal judges to be wrongfully detained...

And despite knowing how many people we are innocently imprisoning, the Obama administration continues to demand the power to imprison people with no judicial review: by indefinitely detaining them without charges, by insisting that Bagram detainees captured outside Afghanistan have no habeas rights, by refusing to release any Yemeni detainees at Guantanamo, including those whom the administration itself knows are being wrongfully detained...

It's commonplace to label something a travesty of justice, but who can deny that knowingly imprisoning innocent people for years and years while scheming to deny them all judicial review is a disgrace of historic proportions?

How to carve half a calf's head for dinner

And you thought it was hard to carve a turkey.  These directions, from "The Housekeeper's Book" of 1837 detail how to cut the various parts off from the head:  "handsome slices" from the cheek, "sweetbread" (??thymus) from the throat, the eye..., the palate...

I found this most interesting:  "There is a tooth in the upper jaw, called by some the sweeet tooth, very full of jelly..."  I wonder if this has any connection to the term "having a sweet tooth" meaning to desire sugary foods?  And I don't understand how a calf's tooth could be sweet with jelly unless there's a high fat content in the roots of the tooth???

Did Botticelli depict Venus and Mars high on drugs?

David Bellingham, a director at Sotheby's, showed this painting to horticulturalists at Kew, who identified the plant in the lower right corner as Datura stramonium; one side effect of its ingestion is the urge to remove one's clothes.
"The fruit is being offered to the viewer, so it is meant to be significant. Botticelli does use plants symbolically."
Personally, I'm not convinced, but it does make the painting more interesting.  The standard interpretation of the painting is here, including this:
The wasps may be a reference to the clients who commissioned the painting. They are part of the coat of arms of the Vespucci family, whose name derives from vespa, Italian for wasp.

Russia has truly adopted American-style "democracy"

The release of this video shocked many people...
The footage, shot last week in Russia's Duma, the 450-member lower house of parliament, showed three MPs frantically running from empty seat to seat in order to vote for fellow deputies who were playing truant after lunch...

"Usually, voting in parliament takes place at the end of a session when the cameras have left and the journalists are not in the chamber." This time was different though and a cameraman from Russian TV channel Ren TV caught the farce on camera in a video which went viral on the internet.

One unidentified MP was caught voting nine times. Critics said the abysmal turnout technically made the vote illegal since the rules of parliament itself stipulated that a majority of MPs needed to be present for its activities to be legitimate.
I wasn't surprised, because I remembered a similar video I posted last April...

That's the Texas legislature doing the same thing.

Starry sky

This is what everyone could see if it weren't for man-made light pollution.

Description from APOD:
What's happening above the Cotopaxi volcano in Ecuador? Quite a bit, from the looks of the above one-night, time-lapse movie, taken earlier this month. The majestic volcano is first seen through breaks in fast moving clouds as the movie begins. Soon the clouds have dissipated and a sky filled with stars seems to rotate about the snow-peaked volcano's peak. The band of our Milky Way Galaxy, the dark Coal Sack nebula, and the Southern Cross can all be seen overhead. Satellites streak by from several directions. Soon thin clouds roll by and seem to make the brightest stars sparkle. On the volcano (starting at about 1:13 of the movie), the lights of climbers flash. Near the end of the movie, a bright airplane passes over the peak with a residual trail seen drifting away.

Purging evangelical Christianity from the Pentagon

"Good morning Mikey, you f*** Jew. Let me be the first to call you a f*** Jew today."

Michael L. "Mikey" Weinstein shares his hate mail with both friends and strangers the way elderly people show off photos of their grandkids. He has plenty of it to share. For the past four years, the founder of the Military Religious Freedom Foundation (MRFF) has been doing battle with a Christian subculture that, he believes, is trying to Christianize the U.S. armed forces with the help of a complicit Pentagon brass. He calls it the "fundamentalist Christian parachurch-military-corporate-proselytizing complex," a mouthful by which he means holy warriors in contempt of the constitutional barrier between church and state...

Weinstein filed a complaint, in response to which the Air Force launched an investigation that revealed a top-down, invasive evangelicalism in the academy. Among other things, it revealed that the commandant of cadets taught the entire incoming class a "J for Jesus" hand signal, that the football coach had draped a "Team Jesus" banner across the academy locker room, and that more than 250 faculty members and senior officers signed a campus newspaper advertisement that proclaimed: "We believe that Jesus Christ is the only real hope for the world." Weinstein has been a First Amendment vigilante ever since...

False memories and "recovered" memories

It was a vivid story, told with sincerity and emotion. But the events Chris described had never happened. Chris's elder brother, Jim, had made it up as an assignment for Loftus' cognitive psychology class. Jim, pretending the story was real, had fed Chris the basics—the name of the mall, the old man, the flannel shirt, the crying—and Chris, believing his brother's fabrication, had filled in the rest. He had proved what Loftus suspected: If you were carefully coached to remember something, and if you tried hard enough, you could do it.

And this was just the beginning. In the years to come, Loftus and her colleagues would plant false memories of all kinds—chokings, near-drownings, animal attacks, demonic possessions—in thousands of people...

Loftus set out to prove that such memories could have been planted. To do so, she had to replicate the process. She had to make people remember, as sincerely and convincingly as any sworn witness, things that had never happened. And she succeeded. Her experiments shattered the legal system's credulity. Thanks to her ingenuity and persistence, the witch hunts of the recovered-memory era subsided.

"The Bourne Identity"

I suspect everyone reading TYWKIWDBI has seen this movie.  The book came out 30 years ago (!), and I remember reading it late into a night because it was - literally - one you couldn't put down.  So I decided to give it another try, thinking I could just whip through it since I've seen the movie recently.

To my surprise, I discovered that the book is quite different from the movie.  In the novel, Jason Bourne is trying to dodge Carlos the assassin and his minions, as well as the authorities; Carlos isn't even involved in the cinema version as best I can remember.  And there's surprisingly little high technology.  Witness this sentence:
"Jason kept his eyes on his watch, the infinitesimal jumps of the thin, delicate sweep hand too agonizingly slow."
I picture a whole new generation of readers asking "Daddy, what's a 'sweep hand'?"  Except the "new generation" won't read the book; they'll only see the movie. 

It's still an excellent book.  Even if you've seen the movie.

R.I.P. Phoenix Mars Lander

NASA has pronounced it "officially dead."
In late 2008, NASA's Phoenix lander dropped into deep hibernation at the onset of Martian winter, concluding a successful and long-running mission. But there was some hope that, despite not being built for such hostile temperatures, the craft would emerge from the thaw with a pulse. A final checkup from the Mars Odyseey orbiter circling overhead last week, however, has erased all hope--Phoenix's solar panels have been frozen off. It's dead.

This photo, taken by Odyssey's orbiting companion, the Mars Reconnaissance orbiter, clearly shows a dark shadow where Phoenix's reflect-y solar panels used to be. Hundreds of pounds of ice were projected to build up on the craft over the winter, which proved too much for its solar panels to maintain structural integrity.
Way to go, little guy. Job well done.

The mystery of portolan charts

... one of the world's greatest and most enduring mysteries: Where and how did medieval mapmakers, apparently armed with no more than a compass, an hourglass and sets of sailing directions, develop stunningly accurate maps of southern Europe, the Black Sea and North African coastlines, as if they were looking down from a satellite, when no one had been higher than a treetop?

The earliest known portolan (PORT-oh-lawn) chart, the Carta Pisana, just appears in about 1275 -- with no known predecessors. It is perhaps the first modern scientific map and contrasted sharply to the "mappamundi" of the era, the colorful maps with unrecognizable geography and fantastic creatures and legends. It bears no resemblance to the methods of the mathematician Ptolemy and does not use measurements of longitude and latitude.

And yet, despite it's stunning accuracy, the map "seems to have emerged full-blown from the seas it describes," one reference journal notes. No one today knows who made the first maps, or how they calculated distance so accurately, or even how all the information came to be compiled.

"The real mystery is that if you took all the notebooks from the sailors used in making these charts, along with the coordinates and descriptions," Hessler says, tapping the glass that covers the ancient vellum, "you still couldn't make this map."

"The ancient Greeks and Romans had traditions of map-making, there's Ptolemy, and there's a line of progression," Hessler says. "But here, it just explodes out of nowhere. It appears to be a true invention of the Middle Ages."

The maps usage began to come to an end during trans-Atlantic exploration. For all their regional accuracy, the mapmakers did not know how to calculate for the curvature of the earth on a flat map. Across the Mediterranean, they could take you from port to port because the distances were comparably small. Over the distance of the Atlantic, if you set out for modern-day Miami, you'd wind up on Long Island.

Still, they were reliable guides to the known world for 400 years, and they have concealed the secrets of their origins and methods for another four centuries, leaving the answers to the realm of novelists and storytellers.

"Airplane!" is a spoof of one movie - "Zero Hour"

I had always assumed it was a spoof of generic disaster movies, but as the video clearly shows, it was based on the plot of the 1957 movie "Zero Hour," often utilizing the same dialogue.  The creators of this movie accidentally videotaped the 1957 movie when they set up their VCR to tape late-night commercials they could spoof.

Mark Twain's autobiography to be published

Twain had specified that his autobiography remain unpublished for a century after his death, to ensure that he felt free to speak his "whole frank mind", knowing that when his "Final (and Right) Plan" for relating the story of his life was eventually published, he would be "dead, and unaware, and indifferent". The author passed away on 21 April 1910, and this November, the University of California Press will publish the first volume...

Running to half a million words, the trilogy of books will cover Twain's relationship with his secretary Isabel van Kleek Lyon, his religious doubts and his criticisms of Theodore Roosevelt, according to the Independent.
I'm looking forward to reading this set of books.  Those who are familiar only with his jumping frogs and boys on river rafts should read The War Prayer (also published after his death) or Letters From The Earth (published despite protests from his family) to get ready for this autobiography.

Hiking a glacial drumlin

Here in the Midwest, you can see lots of glacial landforms as you drive rural roads (or Interstates).  I've always been fascinated by tall drumlins and moraines.  Some on public land can be climbed; others are inaccessible private property.  This past week I had an opportunity to explore one just north of the Madison area.

Empire Prairies State Natural Area is a set of three Wisconsin DNR-managed remnant prairies, one of which is called the Westport Drumlin.  The topography of the drumlin is such that it has NEVER been farmed, and thus is home to a variety of native plants that are difficult to find elsewhere.
Oriented on a northeast to southwest-oriented glacially sculpted ridge is Westport Drumlin Prairie -- a small but diverse prairie containing more than 100 native plant species. A small area of oak opening, with open-grown bur oaks, occupies the western point of the ridge. Although the drumlin wears a thin mantle of glacial till, as evidenced by rounded boulders scattered about, limestone bedrock fragments and small outcrops at the drumlin’s summit attest to the limited terra-forming action of glacial ice on this ridge. Several showy plant species are present including pasque flower, cream wild indigo, rough blazing-star, yellow coneflower, shooting-star, bird’s-foot violet, compass plant, rosinweed, goldenrods, and asters....
The opportunity to visit was afforded by the Madison Chapter of The Wild Ones, in conjunction with the Good Oak Ecological Services restoration consultants, who provided a knowledgeable leader for the venture.

Access to the drumlin was not as easy as the top photo might suggest, because it is surrounded by private farmland which is actively managed, and there are no cleared or marked trails to access the landform.  We were extremely fortunate that our visit coincided with a) the corn having already been planted and sprouted, so we could traverse a field without stepping on or being impeded by the crop, and b) the hayfield (top photo) having just been cut, because the alternative would have been to follow the treeline between fields, where you know the farmers for the last century have been dumping the large rocks from the fields; it would have been a difficult trek. 

As we reached the ridgetop, we were surrounded, even at this relatively early point in the season, by a wide variety of wildflowers.  The presence of large clumps of hoary puccoon (left) was testimony to the virgin nature of the landscape, because the plant is difficult to propagate artificially.   A lot of the unique flora was just emerging, but one notable one was already past its peak.  Pasqueflower (Pulsatilla) is an uncommon perennial that is one of the first flowers to bloom in the spring (typically around Easter - hence the "passion" flower designation).  I have walked the UW Arboretum each spring trying to spot the elusive blooms.  Here atop the drumlin we were surrounded by a sea of pasqueflowers going to seed:

At the very crest of the drumlin we followed a footpath that has been shared by wildlife and humans certainly for centuries.  Because the drumlin affords a vantage point for spotting wildlife in the surrounding area, it must have been a favored location for the earliest humans to settle here after glacial retreat, and would have been a strategic location for Native American hunters; I have no doubt that lots of points and shards and flakes could be found in the soil.  There were several holes in the drumlin large enough to accommodate a coyote, though no evidence of recent digging.

The skull was picked clean and sunbleached; I don't know the species.  An elderly lady who joined us for the field trip suggested it was probably from a deer.

The drumlin will be revisited by this group on August 12, when the autumn wildflowers should be maxing out.  Those in the  Madison/south-central Wisconsin area interested in that trip or in other future walks might want to bookmark this link.

How thresher sharks use their tails

Thresher sharks... possess the classic shark body plan, but there is one feature that immediately stands out when you look at them - their ludicrously elongated tails. What could such an appendage be used for? Does it help them in propulsion, or do they use their tails as a whip to stun fish before consuming them?

The second method, by contrast, involved the shark swimming up alongside its prey and whipping its tail sideways to strike with the distal end of the tail, and this technique was successful about 92% of the time. What had been presumed for so long turned out to be true - these thresher sharks attempted to shock or immobilize their prey with their tails before consuming it.

Scorpion bombs and other unconventional weapons

I've just finished reading Greek Fire, Poison Arrows, and Scorpion Bombs. Biological and Chemical Warfare in the Ancient World by Adrienne Mayor (Overlook Press, 2003).  It has a lot of interesting information; here are some of my notes, with page references.

“Poison and arrows were deeply intertwined in the ancient Greek language itself. The word for poison in ancient Greek, toxicon, derived from toxon, arrow. And in Latin the word for poison, toxica, was said to derive from taxus, yew, because the first poison arrows had been daubed with deadly yew-berry juice. In antiquity, then, a “toxic” substance meant “something for the bow and arrow.” (41)

“… despite the thick leathern cuirasses [the Spanish conquistadors] wore to deflect the arrows, many early explorers died from weapons coated with deadly frog slime, or the plant toxins strychnine or curare… In the Amazon rainforest, natives carried as many as six hundred tiny curare darts in a quiver, and there were horrifying reports that curare was not only used on projectiles, but in hand-to-hand combat too: it was rumored that the natives painted their fingernails with the toxin.” (71)

“Solon, the great sage of Athens, diverted the channel from the River Pleistos so that it no longer ran through Kirrha… Solon then threw “a great quantity of hellebore roots into the Pleistos.”   When he determined that “the water was drugged enough, he sent it back through the city.” “The parched Kirrhans glutted themselves on the contaminated water, and of course because extremely ill… The men defending the walls had to abandon their positions out of never-ending diarrhea.” (101)

“… when the Philistines captured the Ark of the Covenant … and took the sacred wooden chest to their capital, an epidemic marked by swollen buboes in the groin… decimated the population. The survivors sent the Ark away to a series of Philistine towns, and each was struck with the same epidemic… Does the story of the Ark suggest that the chest might have contained some object, such as cloth, that harbored aerosolized plague germs, or an insect vector that infected the rodents in Philistine territory?” (128-9)

“Heaving scorpions by the basketful at attackers was specifically recommended by Leo VI (AD 862-912) in his famous military Tactics handbook.” Romans may also have hurled pots of assassin bugs at their enemies. (182)

Phoenecians “filled enormous shallow bowls of iron and bronze with fine sand and tiny bits of metal. These pans they roasted over a great fire until the sand glowed red-hot.” Then they catapulted the burning sand over the Macedonians… “The molten grains and red-hot shrapnel “sifted down under the soldiers’ breastplates and seared their skinwith the intense heat, inflicting unavoidable pain.”

Greek Fire burned in water and may have been ignited by water, and it adhered to victims. Besides distilled naphtha, the ingredients may have included thickeners such as resin or wax, quicklime, sulphur, turpentine, and saltpeter. The exact formula matters less than the amazing delivery system, which was capble of shooting liquid fire from swiveling nozzles mounted on small boats…” (242) “Perhaps inspired by the celebrated statue of Hercules… public executions by the tunica molesta, a naphtha-soaked “shirt of torture,” became a popular diversion....  Executions “a la Hercules” continued to be staged for the amusement of Roman audiences through the third century AD.” (250)

A sharecropper and his family

The Virgin Mary spanking The Baby Jesus

The proper title is The Blessed Virgin Chastises the Infant Jesus Before Three Witnesses: André Breton, Paul Éluard, and the Painter, painted by Max Ernst in 1926.  According to a Time magazine story in 1976 -
His father was a fiercely authoritarian Roman Catholic, an amateur painter who taught in a school for deaf-mutes in the Rhineland town of Brühl. Little Max briefly persuaded this eccentric sire that he was the child Jesus. Memories of this sort underlie Ernst's most notorious thrust of anticlerical wit, a spanking Madonna...
The painting is (not surprisingly) said to have been controversial at the time.  Now it hangs in the Metropolitan Museum of Art   Ludwig Museum in Cologne.

The net worth of U.S. presidents

A fascinating compilation of data has been assembled in this article at The Atlantic.
Having examined the finances of all 43 presidents (yes, 43; remember, Cleveland was president twice), we calculated the net worth figures for each in 2010 dollars. Because a number of presidents, particularly in the early 19th Century, made and lost huge fortunes in a matter of a few years, the number for each man is based on his net worth at its peak.

We have taken into account hard assets like land, estimated lifetime savings based on work history, inheritance, homes, and money paid for services, which include things as diverse as their salary as Collector of Customs at the Port of New York to membership on Fortune 500 boards. Royalties on books have also been taken into account, along with ownership of companies and yields from family estates.

The net worth of the presidents varies widely. George Washington was worth more than half a billion in today's dollars. Several presidents went bankrupt...

One of the most important conclusions of this analysis is that the presidency has little to do with wealth. Several brought huge net worths to the job. Many lost most of their fortunes after leaving office. Some never had any money at all.
For the data on each president, see pages 2-5 at the link.

The fascinating biology of the Argonaut octopus

The video is silent, so you will need to read the text at Not Exactly Rocket Science for the complete story.  Here are the introductory paragraphs:
The argonauts are a group of octopuses unlike any other. The females secrete a thin, white, brittle shell called the paper nautilus. Nestled with their arms tucked inside this beautiful, translucent home, they drift through the open ocean while other octopus species crawl along the sea floor. The shell is often described as an egg-case, but octopus specialists Julian Finn and Mark Norman have discovered that it has another function – it’s an organic ballast tank...

An argonaut uses its shell to trap air from the surface and dives to a depth where the encased gas perfectly counteracts its own weight, allowing it to bob effortlessly without rising or sinking. Finn and Norman filmed and photographed live animals in the act of trapping their air bubbles, solving a mystery that has been debated for millennia...

Television programs of 1978

This 9-minute segment of CBS' 50th anniversary television special introduces the celebrities associated with that network.  Back in 1978 I had just moved to Kentucky and started a new job; there was no internet and there were no personal computers, and cable TV was in its infancy, so we had time to watch television.

I kept track during this video and discovered I could remember over half of the 100+ personalities showcased.  If an equivalent video were shown with 2010 programs, I'd probably recognize less than 10% (unless it was the Weather Channel).

Found at the ever-interesting Miss C Recommends, where those of you younger than me may find more familiarity in the equivalent program for NBC from 1986.

"Scaly Robigo, god of rust, spare Ceres' grain..."

A mutant fungus is threatening world wheat crops.  Here are some excerpts from a StarTribune article:
The enemy, Puccinia graminis, is a new mutant strain of fungus... Nicknamed Ug99 after it was discovered in Uganda in 1999, this new race of stem rust is the rabbit of cereal grain pathogens -- creating new generations of spores in a matter of weeks. It has crippled wheat farms in East Africa and jumped across the Red Sea to Yemen and Iran...

"By way of the prevailing winds, we're now afraid that if Ug99 gets a beachhead in the Middle East, it can spread to the breadbaskets of south Asia, Pakistan and India.  "That," he said, "would be absolutely devastating for the world's wheat and economy."

Eighty percent of the world's wheat and 95 percent of the Upper Midwest region's top bread-baking grain is vulnerable to the new pathogen..

"With some other rusts, you might see yield losses of 10 percent or 40 percent in a worst-case scenario," Anderson said. "This new stem rust can virtually wipe out a crop."

Their battle is nothing new. Centuries ago, Romans held an annual festival around this time of year just as rust would have taken hold on grain stems in Italy. They would sacrifice a dog and sheep and pray to the rust god to leave their crops alone.

"Scaly Robigo, god of rust, spare Ceres' grain," the ancient Roman poet Ovid wrote. "Let silky blades quiver on the soil's skin ... and keep scabrous hands from the harvest."

The Monarchs have arrived in Wisconsin

Yesterday I captured this image of a female ovipositing on a newly-sprouted milkweed.  When you see a butterfly visiting a non-flowering plant, it's obviously not nectaring.  It may be basking in the sun to recharge its solar batteries, or, as in this case, depositing eggs.  Monarchs curl the abdomen down briefly to just touch the plant and place a single egg.

The white egg itself (click photo to enlarge) is actually sort of camouflaged because it looks like a droplet of milkweed sap exuding
from the plant.  And since the sap is relatively toxic to most insects, it probably looks less attractive.

These photos were taken at the edge of a field which a farmer is in the process of enlarging to accommodate a larger corn harvest.  Unfortunately, he has extended it into a patch of milkweed that has been growing there for a long time (it takes several years for a milkweed to build up a root system sufficient to support a flowering several-foot-tall plant).
He tilled the field a couple weeks ago.  The milkweed are sprouting right on schedule, but they are doomed because he will be back to plant the corn quite soon.  The milkweed will get disced under at that time and likely not resprout.  This is sadly representative of what is going on around North America, as traditional Monarch (and other butterfly) habitat is lost to agriculture (and homebuilding).  I would encourage those of you who are interested (and blessed with a yard/garden) to consider growing plants that support butterflies either as food for their caterpillars or as flowers for their nectar. 

"The Euro as we know it" is dead

Excerpts from an interesting (and rather vehement) article in the Telegraph:
The euro has many flaws, but its weakest link is Greece, whose fundamental problem is that for years it spent too much, earned too little and plugged the gap by borrowing in order to enjoy a rich man's lifestyle. It flouted EU rules on the limits to budget deficits; its national accounts were a moussaka of minced statistics, topped with a cheesy sauce of jiggery-pokery...

What was once deemed unthinkable is now, I believe, inevitable: withdrawal from the eurozone of one or more of its member countries. At the bottom end, Greece and Portugal are favourites to be forced out through weakness. At the top end, proposals are already being floated in the Frankfurt press for a new "hard currency" zone, led by Germany, Austria and the Benelux countries. Either way, rich and poor are heading in opposite directions...

Greece's severe difficulties were home-made. The euro has come under pressure not from dark forces of speculation but respectable investors, many of them traditional pension funds, which, quite correctly, worked out that when the crunch came, the Brussels elite would sanction an abandonment of its no bail-out rule and cough up for a messy fudge...

Protecting the euro has become a project via which profligate states dip their fingers in Berlin's till. Germany is taking on nasty obligations without gaining ownership of the assets. Germany's version of The Sun, Bild Zeitung, feeds its readers a regular diet of stories about the way ordinary Germans are being taken for mugs. Trust has turned to suspicion. Next stop is divorce...
