This big beetle banged against our window 6/5/2016 and then sat quietly at the bottom of the sill. I caught it in a small vase without a fight, checked it out and let it go. What is it? It was really cool! Its claws clicked against the glass I caught it in and it turned itself into its back. It had a had time turning itself back over- I don’t think it was defense.

Hi Jeff,
This is a California Root Borer, and we just posted our first sighting of the year two days ago.

Thanks! Makes perfect sense surrounded by grapes and deciduous trees.

    We just found a dead California Root Borer in our driveway this morning in the Santa Cruz Mountains off Old Santa Cruz Hwy. about 7 miles from Los Gatos. We have a lot of coast live oaks, madrone, Douglas fir, and redwoods in this area.
