Wingless Scorpionfly (Apterobittacus apterus), Windy Hill Open Space Preserve, San Mateo County, California - 1 June 2013. Crawling awkwardly but quickly across the Spring Ridge Trail this morning. I thought this was a walkingstick, but v belov and the balabans from Bug Guide kindly provided the correct ID. A crappy photo, but my first from this order of insects. Supposedly this species is fairly common in grasslands in the Bay Area.
