leafhopper - Sophonia orientalis

leafhopper - Sophonia orientalis
San Leandro, Alameda County, California, USA
August 14, 2004
Size: 3-4mm
Cicadellidae

The dark spots on its wings had me fooled at first--I thought those were the eyes, until I looked more closely.

I found several of these on grape leaves in my yard. There is a high likelihood that it's not native--many insects in my Bay Area yard aren't native. I wasn't able to find it at the Essig Museum collection--maybe I missed it. I thought it would be (sort of) easy because of the markings.

Sophonia orientalis
Identified as Sophonia orientalis by Andrew Hicks. (Thanks Andrew!) It's an invasive species in California and Hawaii.
The reference is Webb, M.D. & C.A. Viraktamath. 2004. On the identity of an invasive leafhopper on Hawaii.

A synonym for Sophonia orientalis is Sophonia rufofascia. Here are two sites with more information:

Cool! I've seen similar false eyes on the hind end of adult spittlebugs (Dogwood Spittlebug, for example). http://bugguide.net/node/view/23220
