I think it was out and about shortly after a rain. In 35 years in this state, I've seen only two termites. (The other was last year, winged and the dry type.)

Thanks, Joyce, for the ID and info.

That's "big" so it's probably Zootermopsis angusticollis. I don't know if you have any others in that family where you are; you might wait for someone else to chime in.

If you take an evening walk in the woods the day after a rain in the fall, you have a good chance of encountering a swarm -- hundreds pour out of rotting wood and fly around bumping into you. It's quite something to see. There was a swarm on the UC Berkeley campus a few weeks ago -- there were hundreds flying around on my way to get lunch, then 15 minutes later in the same area they weren't there anymore (at least they were not so evident; I didn't look hard).

The swarm sounds impressive; hope I see one eventually.

We've had a lot of wood damage to our house over the years and, while everyone else says "Termites!", I haven't seen any. Instead, ants are what I find noshing on our woodwork.

I think it's a termite.

That clinches it, as far as I'm concerned. Termite's on the move!
