I think it could be an isopod but am unsure. It doesn’t look like ones I am familiar with in houses (usually basements, which is not where this is).
It is about 10mm or 3/8" long, seems to move towards the top of the picture (but mostly is just wiggly), and is slightly hairy. Western USA.
I sometimes see these (or at least, something that looks like it) under my dog’s water bowl every now and then. I do not know what they are, or where they come from but they do leave carapace shells and some kind of silk cocoons all over the place which is gross.
Just commenting to follow this for the answers because I would also like to know.
