Not captive.

I found this walking today,
I saw these deep red ants next to a pyramid, but the pyramid was not their nest, but next to it.

Trachymyrmex septentrionalis.

Don't worry, she is refrigerated.
once she became active I recollected her, and went back to replace her, and snapped a picture of the nest.
So some quick reading, This is actually a common species here, (ohh well) but a very beneficial one, found in a wide variety of habitats.
This habitat is the oldest building in the city, (1840s) with an absolutely lush vegetative yard. This yard features a lot of old, very loved plants. Lots of bare dirt covered in rich silt, and leaf litter. NOT A BLADE OF GRASS, these guys clearly like ground cover and disdain the fertilizer requiring grass lawn. and is the place I have found several species, including the Tapinoma sessile super colony on moving day. (I can only look from the sidewalk, I don't know the owner.)

This small colony won't get very big, as this species is supposed to be a fungus grower related to the leaf cutter. In fact often put in the same tribe. But these guys do it on a much smaller scale. Instead of defoliating entire orchards, they harvest insect poop, bird poop, and decomposing leaf litter.
This is also a small colony, even for the species.
Here is their crescent pyramid/ziggurat , Just up from it you can see the nest hole. very discreet. That black dot.

There are two ants in the nest picture.
one is a bright red (slight blur), the other is more burgundy (just the head poking out of the nest.)
I would have tried to get a better picture, but I don't want to loiter next to someones house, I can try and get a picture after work (on route) one day next week (rain all this week) If you guys want.

Ohh, here is their closest neighbors.
without checking under microscope, or with a macro lens. I'd guess some sort or Monomorium.

I only mention this because it is 5 inches downhill from the ziggurat.

At work, Any house that prefers moss and ground cover over traditional grass lawn, and every two feet ON THE PATH through the woods.

Here is a swarm cutting up....(I assume a dead insect)

Hope you find a queen of that species. That would be cool.

I should clarify. I hope you catch a queen of that species. I've found plenty of queens that got away. :(
