butterfly larva - Hemileuca eglanterina

butterfly larva - Hemileuca eglanterina
Nicasio, Marin County, California, USA
May 6, 2007
Size: 3 cm
Found on manzanita (but no sign it was eating it). Close to oak/bay/madrone woodland with some Douglas firs.

Moved from Butterflies.

Check out Hemileuca eglanterina, a day flying moth. It found in your area and just a note, the caterpillars have hairs what sting like nettles.


If you guys are correct, this is new to the guide, as it seems we only have adult images of that species so far.

I'm thinking Nymphalidae: Nymphalinae, but I don't have anything beyond that....I'll keep looking though. Absolutely beautiful!

Thanks for looking. I've seen it once before on Ceanothus. Only adults flying in the area were variable checkerspots and brown elfins - and it's not either of those.

It says that the host for the California Tortoiseshell is Ceanothus, so I'm pretty sure that's what this is...but it may be something else. When it comes to caterpillars, I generally stick to Sphingids and Saturniids :).

That was quick!!!
I think I have it. California Tortoiseshell (Nymphalis californica). This looks like the early instar as found in Caterpillars in the field and garden, by Thomas J. Allen et al.

Thank you!
That would fit with Ceanothus! And there was some in the area along with the manzanita I found this on. I appreciate your help!
