Found a few of these in my bathtub… I believe they came in through a crack in the grout.
Teeny, tiny little things. Like smaller than a tick. It was difficult even to focus the camera on one of them and I didn’t think to try and get something in the frame for scale. The pictures are zoomed in quite a bit, so they look bigger than they actually were. Sat here for a while trying to think about what to compare them to for size… then I looked at my phone. They were right about the size of one of the dots on the little horizontal scroll bar at the bottom of the pictures I’ve posted. Central Indiana, just north of Indianapolis.
