Differences between males and females are the norm among ants. This male ant is tiny at 3 millimetres long. For the longest time, I had not the foggiest idea what this was other than a wasp-like animal. Thanks to the iNaturalist community it was identified.
Male ants are a rare sight, emerging only at the right season and only for a brief period of time. It is said that most die shortly after mating.
Stigmatomma sp, possibly S. denticulatum. https://www.inaturalist.org/observations/88809662
