Wasp Deposits Parasitic Larvae Deep Inside Tree Trunk
The giant ichneumon wasp, megarhyssa rixator, has an unusual method for laying eggs. Using her overly-long ovipositor to drill deep into a tree trunk, she deposits a single egg on to the surface of an immobilized wood wasp larva. Her egg turns into a larva, that will eat the paralyzed host...bit by bit.
