  1. #Arachtober 14: A wasp's progress. Over a few weeks in July, I saw a cobweb spider on a fire hydrant parasitized by a wasp larva, then the wasp's pupal cocoon, then at last the empty cocoon.

    Some parasitoid* wasps alter the spider's behaviour to make them spin a web more suited to sheltering the pupating larva; not sure if this was the case here.

    There are also hyperparasitoids that target parasitoids, so for all I know the wasp itself may have been parasitized and a different species emerged!

    * "Parasitoid" means a type of parasite that eventually kills its host rather than simply feeding on it. Your typical parasitoid is a solitary wasp that lays eggs on hosts which become larvae that devour the host, often from within.
