Pupa of Caterpillar Parasitoids
Copyright © 2013 Sean McVey

Pupa of Caterpillar Parasitoids
Basking Ridge, Somerset County, New Jersey, USA
May 25, 2013
Size: 5-6 mm
Not sure when these things emerged, but I just noticed them today (2 days after I found the Cat). There's only 6 even though there was a total of black dots. (This may be because I poked at one black dots with a pin to see I could get anything to come out. Nothing happened and I stopped to avoid killing the caterpillar, which seemed fine.)
It looks like the larva tore big holes on their way out.
Any ideas of what they'll turn in to? (Most likely a wasp or fly...)

Flies
These are fly puparia. The spiracles are more pronounced than I'm used to seeing on tachinids, but offhand I can't think of another fly family that parasitizes caterpillars.

Also Sarcophagidae
Sarcophaga aldrichi is a caterpillar parasitoid and I expect other Sarcophagidae are too.
