Parasitoid Wasp - Family Braconidae I collected a casebearer (Coleophora atromarginata) larva on 5/16/25, and it appeared to pupate a few weeks later. I&#039;ve been waiting for the adult moth to emerge ever since and nearly gave up, thinking it had died.

Parasitoid Wasp - Family Braconidae

I collected a casebearer (Coleophora atromarginata) larva on 5/16/25, and it appeared to pupate a few weeks later. I've been waiting for the adult moth to emerge ever since and nearly gave up, thinking it had died. But, on 7/17/25, this tiny, parasitoid wasp emerged from the case instead of the moth that I had been anticipating.
