I just found this bug in my room and wondered if it was an ant or not. She has a stinger! I didn't know ants have stingers.
1. Lynnwood, Wa. USA. In my bedroom climbing a wire.
2. 9-21-16
3. Unknown. Found in my room.
4. 6mm. She is standing on a pencil eraser for comparison.
5. Black gaster and head. Red abdomen. Shiny, no hairs or very small possibly.
6. What looks to be a stinger coming out of the end of her gaster. Also her antennal segments are different from the ants I have seen so far. There is usually a long one from the head, but this “ant” doesn’t seem to have the one long segment, instead she has small ones from the base of the antenna all the way to the tip.
7. When she felt threatened (trying to get her on the pencil to get her out of my room) she raised and lowered her gaster/stinger section as she walked along the pencil.
8. Unknown.
