Just bought a house in Bermuda Dunes, in the hot desert of Coachella Valley, California. This past three weeks our yard has been inundated with these beetles (please see picture). We’ve tried to identify it by searching the web for a similar picture, but can’t find one. Can you possibly tell us what kind of beetle this is?
Thanks in advance.

This is a Lined June Beetle in the genus Polyphylla, but we are not certain of the species. Based on the species posted to BugGuide, one possible species identification might be Polyphylla cavifrons which is pictured on BugGuide and looks very similar, though BugGuide does note “Species identification often difficult.” We tried searching for the genus in Coachella Valley and discovered an article on Digital Commons that mentions a new species, Polyphylla aeolus, from your area. The images on BugGuide do look similar but they appear to have more markings on the elytra than your individual.
