Monarchs approaching our latitude


Map from Journey North.  We have milkweed plants about 6" high in the front yard, waiting for them, but to my amazement, this year some animals - apparently rabbits - are browsing the milkweed and consuming the leaves.  The plant has so many defensive toxins that I'm surprised to see this happening; I've never seen it before.  Perhaps the immature spikes don't have all the chemical defenses that a mature one harbors.

  1. Looks like they've reached Point Pelee.

  3. Been meaning to send this to you for a while. You probably already know of it but just in case it's news: butterflyexhibitions.org is the website of the International Association of Butterfly Exhibitors and it maintains a list of places that host live-butterfly shows around the world. Just FYI.
