Default Larval identity???

In reviewing the numerous help threads I didn't find one specific for butterfly/ moth larvae; that said, hope this one isn't redundant. Was hoping suunto or others could help with the id of these little fellows enjoying my Aster drummondii.

This is a larva of a sawfly (Hymenoptera: Tenthredinidae), possibly a Macrophya sp. Sawfly larvae may be distinguised by their having fleshy 'prolegs' on the venter of abdominal segments one and two; caterpillars always lack prolegs on these abdominal segments.

I did the same thing when I started...as soon as I saw "sawfly" the term "prolegs" immediately popped into my head. Seems I must've learned *something* last year.

It is still a great idea. "Larval Identity" works fine--lots of different larvae out there.

I spotted these on one of my quaking aspens. Any ideas?

These appear to be early instar caterpillars of the Io moth, Automeris io (Lepidoptera: Saturniidae). They feed gregariously at all stages, and change color dramatically as they mature. See IO Moth Lifecycle; Automeris io for details on their life cycle.

Ok, what is a "proleg?"

"Prolegs" are fleshy unsegmented structures that occur on some abdominal segments of the larvae of nearly all true caterpillars, larvae of some Hymenoptera in the suborder Symphyta, and even larvae of a few species of true flies (order Diptera). These structures are used not so much for locomotion as in true legs (which only are found on thoracic segments) as in grasping the substrate (especially objects like twigs and margins of leaves) that the insect occupies. See Proleg - Wikipedia, the free encyclopedia for more details.

I'm confused. In the post of yours above you stated "Sawfly larvae may be distinguised by their having fleshy 'prolegs' on the venter of abdominal segments one and two; caterpillars always lack prolegs on these abdominal segments."

But here in this post you're saying ""Prolegs" are fleshy unsegmented structures that occur on some abdominal segments of the larvae of nearly all true caterpillars,..."

Thanks, suunto. As soon as I read "Io moth" I knew they were cool looking. I could picture the false eyespots. What a great addition to our evolving habitat.
