  Ichneumon Wasp
The body of the wasp is nearly 1 1/2 inches in length, but the ovipositor of the female can be nearly 5 inches in length, and though it can pierce several inches of wood, humans need not fear since it is not used for stinging.
The female Ichneumon uses her ovipositor to lay her eggs in wood where the young grub locates wood boring beetle grubs and feeds on them.
The female wasp lays her eggs inside the caterpillar and the young feed on the living host, eventually pupating within the caterpillar which soon dies.
