Unknown Caterpillar - Idia

Unknown Caterpillar - Idia
Geneseo, Henry County, Illinois, USA
June 2, 2005
Size: 4 cm
I found this caterpillar under a rotten log. Any ideas?



Old post but just wanted to say
I stumbled on this just now and am inclined to agree with the contributor that this is a caterpillar; that sure looks to me like a rounded head capsule on the right end of the animal.

Moved from Syrphid Flies.

syrphid larva?
Reminds us of syrphid larva. check here

No way most syrphid larvae get to 4 cm. I would like to have Martin Hauser or another dipterist to look at this. I'm not even convinced it IS a dipteran, though a crane fly larva might be a better prospect.
