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.
