Hello everyone,

Caught a couple ants on my blacklight tonight. They both look like tetramorium immigrans, first picture a queen second a drone. but both a little larger than I'd expect, plus both at night I thought tetramorium usually flies in the morning.

Size, first picture about 8mm. 2nd picture about 6.5mm.
Both mostly black with brownish legs.
I live in a neighborhood with a lot of surrounding woods.
Flight date 7/12/25 around 10pm
Southeast Wisconsin.

Definitely a tetramorium immigrans.

Definitely a tetramorium immigrans.

Completely agree. Easily the most abundant species flying in the US at this time.

Thanks guys I thought so too. Was just surprised to find them at night on my blacklight. I've only seen them in the morning before running around. I guess I've gotten them in my swimming pool too so I suppose they could have been flying overnight.

They fly almost any time of day in my experience, which is why I literally can go outside and look down and there'll be tetra queens.

Makes sense, that's how camponotus and tetramorium have been for me this year. Really hoping some other species later in the year are this easy!

It all depends on where you look.
