I’m not sure what these green caterpillars are. There were hundreds of them in the Coyote Brush (Baccharis pilularis) at the Carpinteria Salt Marsh Nature Park this past weekend.

Unknown Sawfly on Baccharis

Skeletonizing Leaf Beetle Larvae on Baccharis

Hi John,
We will check with Eric Eaton, but we believe these are Sawflies and not Caterpillars. Sawflies are the larval form of a non-stinging member of the order of insects that includes ant, bees and wasps, Hymenoptera.

Update:
Daniel:
Hard to tell from the image, but either sawfly larvae or chrysomelid leaf beetle larvae.
Eric

Update: May 29, 2011
Upon searching for the identity of a Skeletonizing Leaf Beetle on BugGuide, we discovered that these are the larvae of
Trirhabda flavolimbata.
