Wasp eating Monarch caterpillar
I finally found out what was killing my Monarch caterpillars, can you please identify him, I think it is a type of paper wasp. I just moved to southwest Florida and am on my 3d generation of Monarchs in a little garden planted just for them. This little caterpillar was getting ready to form into a Chrysalis on the fence when the Wasp got him. I have found the remnants of them before, but have not caught the culprit. While I love my little caterpillar farm, I won’t get rid of the wasps because I don’t think I can support all of the caterpillars the Monarchs lay on my milkweed. We have a population of Monarchs here year round. I will let nature take its course in my garden. Great site, I love it and have learned quite a bit! Also enclosed is a Potter wasp that changed the color of his pots based on his foundation. Great site, I love it and have learned quite a bit!

Hi Terry,
Good call on the Paper Wasp. It looks like Polistes annularis as pictured on BugGuide. Regarding the Potter Wasp, we doubt that this was a designer choice based on reading Martha Stewart. More likely the mud that was available at the time had a different coloration. This might be Zeta argillaceum, also pictured on BugGuide, but your photo isn’t detailed enough to be certain.

Hi. Saw this wasp whilst on a field trip to Tenerife with the University. Need to identify it for a write up. Any ideas? Thanks

Hi Dylan,
We are relatively certain this is a Paper Wasp. Eric Eaton has this to add: “The wasp is indeed a vespid of some kind, but definitely not Polistes (the specimen in the image has a stalked (“petiolate”) abdomen, whereas Polistes does not. This being a foreign insect, I can’t identify it any further than family, sorry. Eric”

I was hoping you could tell me what kind of wasp makes these dirt “globes”? I saw the wasp, it flew in with a squirming green caterpillar. They wrestled for a bit among the impatients. The wasp won, then proceeded to stuff it’s prey into the top globe. The wasp was small and black with a bit of yellow; sorry I could not get a better picture of it. But you can see it has closed up the bottome two globes which I’m assuming hold prey for eggs inside to feed on?

Hi Sarah,
The Potter Wasp, Eumenes fraternus, is black with yellow spots on face, thorax and abdomen and smoky wings. Adults drink nectar and young eat caterpillars. The female builds the squat spherical chanber of mud on a twig or branch, sometimes lining up several as your photograph indicates. The chambers are filled with anesthetized caterpillars. The chambers are rain-proof.
