Spruce Budworm Parasite
A small brown braconid wasp that is a key natural enemy of the spruce budworm in North American boreal forests. It suspends its cocoon on a silk thread from the host.
Did You Know?
Its cocoon dangles from a silk thread like a tiny pendulum, which may protect it from ground-dwelling predators.
