Found this critter right outside my kitchen window, seemed to move very slowly over the week. Then started growing the dangling things off of his/her body.

Pandorus Sphinx Caterpillar parasitised by Brachonid Wasp

Pandorus Sphinx Caterpillar parasitised by Braconid Wasp

Hi M.,
This is a Pandorus Sphinx Caterpillar, Eumorpha pandorus, and it has been parasitized by a Braconid Wasp. The Brachonid Wasp lays its eggs inside the caterpillar and the larvae feed on the internal organs, eventually emerging and pupating on the outside of the caterpillar. You can see some of the pupae have “hatched” and the adult Braconid Wasps have emerged. Sadly, the Pandorus Sphinx Caterpillar will die.
