Comments & ID Thoughts

I just bought a house in San Antonio TX with a pool in the backyard. Our yard has a greenbelt behind it. I keep finding these in the bottom of the pool. Probably around 10 or 12 of them now.

Tentatively Brachypelma vagans I’ve seen a few in the area, but it’s hard to tell for sure.


Hi, welcome to Spider ID. 🙂 I can’t see some details as well as I’d like but this is likely a South Western Trapdoor Spider (Eucteniza relata).


Pure speculation, but I wonder if the reason is that they are males wandering in search of mates, they sense the water and want to drink but they fall in and can’t climb out.
