Therevid larva plus ?
Santa Cruz, Santa Cruz County, California, USA
March 22, 2015
I'm showing the last image first. I saw the long white thing I think could be a crane fly larva. It was writhing on the ground. I though maybe I had stepped on it accidentally and not noticed. Then I started wondering about the disproportionate amount of guts coming out of the wound, given the larva did not seem to flattened or severed. I could be wrong. But if not severed, could it be something very well camouflaged has attached itself the the larva. A case bearing predator? I doubt I'll get a definitive ( possibly no) answer. But I'm hoping I'll learn something.

Therevid larva
Not sure what is coming out of / gripping onto the thorax there, that is weird and unfortunately these angles don't really help. Maybe someone else can help with that part.

Thanks, Natalie - It does look a lot like the above ...
Therevid larva. For just the early part of spring it seems that stiletto flies, snipe flies, robber flies, and even the occasional small-headed flies are seen. But they seem to go away all too soon. This is the first Therevid larva I've seen. I wish I could have been more thorough but I was a ways away from home, and had to get back. Thanks for pinning down the larva ID. Sure is odd looking!
