Speaking of stinging insects, I photographed these bullet ants at the Milwaukee Public Museum. I found the following information in an Internet report by Randy C. Morgan, Associate Curator of Entomology, Insectarium, Cincinnati Zoo and Botanical Garden: "Paraponera clavata is best known for its giant size and unusually severe sting. Workers are 18-25 mm. (up to 1 in.) long and look like stout, reddish-black, wingless wasps. Their stings are the most painful and debilitating known for any insect (Schmidt 1986, 1990)." Ouch.
