Just thought I'd add onto my post from above because I found this kinda humorous.
Desert field biologist, Justin Schmidt, came up with his own scale for painful insect bites/stings.
It seems that the guy is so dedicated to science, that he willingly submits himself to insect venom, by letting unknown insects bite/sting him. Then he rates the pain that he received.
He said that if a honey bee sting is likened to being gently prodded by a finger on your arm, then a bullet ant bite is like being punched violently in the arm by a closed fist.
About the pain involved from the bullet ant, Justin had this to say, "pure, intense, brilliant pain. Like fire-walking over flaming charcoal with a three-inch rusty nail in your heel." And supposedly the pain from that lasts a full 24 hours.
And of the tarantula hawk's venom he adds, "blinding, fierce, shockingly electric. A running hair dryer has been dropped into your bubble bath."
If you say so Justin, I'll just have to take your word for it. Some guys really do like their work.
