Pepsid from Livermore, CA - Entypus unifasciatus -
Livermore, Alameda County, California, USA June 30, 2012 Size: 2 cm
Not sure if this is identifiable based on these photos, but I'm hoping the wing veination might clue someone in. It seemed a little smaller than some of the pepsids I've seen before. Feeding on Eryngium.
