This ant was found just chilling in our bathroom. It would flee when I approached, but otherwise maintained an eery stillness for an ant. I picked up it and moved it in a jar. I put it outside, thinking it would run and hide, but again, it would run when I touched it and otherwise just sat there, for at least several hours.

I dunno if it's clear in the shot, but the thorax has clearly been de-winged, meaning this must be either a reproductive female or a male. Based on the pictures I found, it seems to look more like a young queen. I later saw others like this, but with wings still attached.
