what is it …
and why did it fly into my kitchen window at dusk? It looks like some cockroaches I saw in Baja many years ago, but I’ve never seen anything this big here just south of San Francisco.
Thank you.

Hi Lynn,
You have been visited by a Pine Sawyer, Ergates spiculatus, also known as the Spineed-Neck Longhorn. Larvae eat the sapwood and heartwood of pines and Douglas firs and adults emerge July – August. I guess the rains brought them out a little early this year. Females are often attracted to lights. Their habitat is usually forests near and above 4000 feet. According to Hogue: “campers in pine flats in neighboring mountains are frequently startled when these beetles loudly buzz into their lanterns on warm summer evenings.”
