Abstract:
Parasitoids - insects that parasitize other insects - have fascinating biologies that have made them darlings of the science fiction genre, owing to their wide array of innovative and often gruesome strategies for living off other organisms. These insects do not sting, but rather lay eggs on or inside their hosts, typically another insect or spider. Unlike parasites, which feed off a host without killing it, parasitoids kill their hosts - and they typically do it slowly. Parasitoids carefully keep their hosts alive for extended periods while they feed on host hemolymph and/or tissues until they are close to completing their own development. The techniques parasitoids use to feed on and manipulate their hosts are wide ranging, demonstrating multiple evolutionary pathways to achieve successful development from egg to adult.
