Braconid Wasp Cocoons

Pupae of braconid wasps. Arroyo Chico, Tucson, Pima County, Arizona, USA. 18 October 2008.

 

I found lots of these in a thicket of climbing milkweed (Sarcostemma cynanchoides) that was frequented by queen butterflies (Danaus gilippus) earlier in the year. I suspect that these wasps emerged from queen caterpillars.
