Hello! the featured picture under the heading Potter wasp, in the upper left hand corner, appears instead to be a fly rather than a wasp. Flies belong to the Order: Diptera (Di: two and Ptera: wings). The featured insect also has short antennae also pointing toward the dipteran category. Wasps on the other hand are in the Order: Hymenoptera (Hymen: membrane and Ptera: wing). They have 4 wings total. Let me know what all you think--it wouldn't be the first time I'm wrong!
