Size: 4 - 7 mm est.
I thought I had posted this previously but I guess I was wrong.

I found a number of these vivid orange grubs in the sapwood of a log section, wondering what kind of beetle they would become. Ha! they turned into little wasps. As these wasps matured at different times I was able to gather three stages for this photo. The imago is freshly emerged from pupa.

I wanted to link this shot of orange wasp larvae to this recently posted shot of lime green larvae that I think might also be wasps, my point being that I think bright hues like these are characteristic of wasps, at least certain kinds of wasps.

Moved from parasitic Apocrita.

Jim, the adult is an ichneumon wasp. I would hesitate to place in this in a subfamily without more supporting details such as wing venation; that being said, this does resemble pimplid wasps which attack the larvae and pupa of many different insect groups.

See reference here.

Thanks, Ross.
I move it to family.
