Braconid wasp cocoons? - Cotesia

Braconid wasp cocoons? - Cotesia
Haydenville, Hampshire County, Massachusetts, USA
April 2, 2012
Size: 3 mm (each cocoon)
I found this cluster of wasp cocoons on a very low blueberry bush (or perhaps other ericad) and brought it home to see what would emerge. Thanks to Tracks and Sign of Insects and Other Invertebrates (Eiseman and Charney, 2010), I predicted braconid wasps, and I believe that's what I found in the jar about 20 days later. I'll post a couple of shots of the little perpetual motion machines. One of the wasps seemed unable to fly for some reason, and I accidentally crushed another while trying not to let them all out of the jar at once, so I dispatched these two in the freezer (if anyone knows a more humane way to put an insect out of its misery, let me know) and got some close-ups to document the things that distinguish them as braconids (antenna, forewing venation, hind trochanters). After everyone had left, I took the cluster of cocoons apart to see if there was any remnant of host underneath, but I found none.
