Thread-Waisted Wasp

September 13, 2018  •  10 Comments


A Thread-Waisted Wasp was foraging on the garlic chives in the late afternoon. These wasps are considered to be extremely strong despite their fragile looking frames. The females dig burrows where they lay their eggs, and then they find a caterpillar, preferably a big fat tomato worm more than double her size, grabs it with her powerful jaws, stings it to paralyze it, then drags it to the burrow where she laid her eggs, stuffs the caterpillar in the burrow, and covers the opening with dirt and rocks to hide her stash. When the eggs hatch, the larvae feed on the caterpillar until they pupate and dig out of the burrow as full grown wasps. Thread-waisted Wasps are not aggressive toward humans, unless the humans in question happen to look like giant caterpillars or, even better, great big plump tomato worms. Thread-Waisted Wasps will sting in self defense — if stepped on or handled roughly, for example.

Thanks, Lavinia!
I learned recently that wasp is a category of exclusion: any hymenoptera that isn't an ant or a bee. I find this to be really interesting. Your mileage may vary.
