Dear TW,
This is a male Cedar Beetle or Cicada Parasite Beetle,
Sandalus niger, which we identified on BugGuide.  According to BugGuide, they are present “mostly: Sept-Oct.”  Of the genus, BugGuide notes:  “antennae flabellate in males, serrate in females” and flabellate is an entomological term to describe fanlike antennae.

Through your site I discovered that I had found a Cedar Beetle. My husband and I are in Littlefield Texas for a few months for a job and this is where I found it. A few days later I went for a walk and saw a large amount of them flying around a tree in our backyard. It was very strange as there seemed to be only one female and the rest were males all trying to mate with her. I have several pictures and videos of them. If you are interested in seeing them I would be happy to send them to you. Also, the following day I was digging to plant a bush and dug up a female. She seemed fully formed but not quite ready for the outside world yet. I wasn’t sure if I should bury her or not so I put her under the bush I planted. A short time later, I saw two males buzzing around looking for her. Thanks for your time reading this and the work you put into this site!
