I thought when I took this picture that this was a fly, but it isn’t. Is it a native California bee? I like those antennae.

This is a male Longhorned Bee in the tribe Eucerini, and we haven’t the necessary skills to taxonomically identify it further. According to BugGuide, they are: “Hairy bees, typically with pale hair bands on the metasoma. Males typically have very long antennae. ” BugGuide also states: “Nesting is in the ground for all species. Known nests are vertical burrows in flat ground.” We have several great images on our site of “bachelor parties” which are aggregations of male Longhorned Bees that spend the night together.
