Sting pain index

"The Schmidt Sting Pain Index is a pain scale rating the relative pain caused by different Hymenopteran stings. It is mainly the work of Justin O. Schmidt, an entomologist at the Carl Hayden Bee Research Center. Schmidt has published a number of papers on the subject and claims to have been stung by the majority of stinging Hymenoptera..."

*1.0 Sweat bee: Light, ephemeral, almost fruity. A tiny spark has singed a single hair on your arm.
* 1.2 Fire ant: Sharp, sudden, mildly alarming. Like walking across a shag carpet & reaching for the light switch.
* 1.8 Bullhorn acacia ant: A rare, piercing, elevated sort of pain. Someone has fired a staple into your cheek.
* 2.0 Bald-faced hornet: Rich, hearty, slightly crunchy. Similar to getting your hand mashed in a revolving door.
* 2.0 Yellowjacket: Hot and smoky, almost irreverent. Imagine W. C. Fields extinguishing a cigar on your tongue.
* 2.x Honey bee and European hornet: Like a matchhead that flips off and burns on your skin.
* 3.0 Red harvester ant: Bold and unrelenting. Somebody is using a drill to excavate your ingrown toenail.
* 3.0 Paper wasp: Caustic & burning. Distinctly bitter aftertaste. Like spilling a beaker of hydrochloric acid on a paper cut.
* 4.0 Tarantula hawk: Blinding, fierce, shockingly electric. A running hair drier has been dropped into your bubble bath.
* 4.0+ Bullet ant: Pure, intense, brilliant pain. Like fire-walking over flaming charcoal with a 3-inch rusty nail in your heel.

Several years ago I stepped in a yellowjacket (2.0) nest while clearing brush. They swarmed me and chased me the quarter-mile back to my car. I have no desire to encounter a creature capable of a 4.0 sting.
