I found this little one on the side of the house. It was about 1 cm long.
We were immediately excited upon viewing your photo. We knew that though this looked like an ant, it is more likely a parasitic wasp and judging by the ovipositor, that the individual is female. We quickly discovered the genus Gelis on BugGuide where we found this matching photo. According to BugGuide: “Many species of Gelis are wingless. Habits are diverse. Many are external parasites of Lepidoptera in cocoons, others are parasitic on Symphyta, spiders, Diptera larvae and pupae, or wood-boring Coleoptera larvae. Many are Hyperparasites.” This is news to us as we did not realize there were wingless Ichneumons.
