Buren’s Pyramid Ant

Another lovely insect whose descriptions online are just stubs of articles. The “remarks” on the Dorymyrmex bureni page on bugguide mention that this ant is not considered a nuisance species as it happens not to shoot formic acid (as do some formicine ants). What a ringing recommendation. They’re brown, they like sandy areas, and they…

Mexican Paper Wasp

Meet Mischocyttarus mexicanus, the Mexican paper wasp. This eusocial species has actually been extensively studied, because individual wasps employ different reproductive strategies over their lifetime, including nesting individually and as a colony, brood parasitism (with unrelated conspecifics) and usurpation. This “reproductive generalization” is unusual behavior. M. mexicanus can be found all over the southern United…

Brown-Winged Striped Sweat Bee

This is actually a male A. splendens; the abdomens of females are metallic green, and their tibia are furry. Sweat bees (family Halictidae) come in a huge variety…

Southern Yellowjacket

This grumpy, chilly southern yellowjacket (Vespula squamosa) would not have let me get this photo if it hadn’t been 55 degrees F outside. She was sunning herself and did not appreciate being photographed; you can see her head turned toward me, and one foreleg half-raised in a very rude gesture. These social wasps are found…

Thread-Waisted Wasp

Originally I thought this was some sort of fly. Then I thought it was a wasp. Then I thought it was a wasp mimicking a fly. /r/insects didn’t know what it was. Months later, while searching for Polistes wasps on google, I scrolled past a picture of a similar species of sand-digger wasp, and —…
