This was shot during an early morning session on October 12th.
I'm not sure what kind of larva this is – hymenoptera or lepidoptera? I'm guessing the former. Moth larvae have several pairs of eyes while sawfly larvae only have a single pair. I was counting on being able to tell this from the images but it turns out to be quite a challenge do discern the number of eyes because of the frost.
