1. Collected in my yard while picking rocks out of the ground.  

2. Collected - 5-17-18
3. Habitat of collection - Dirt.  Maybe a little sand but was under some grass.
4. Measuring from outside the tube (some distortion) it looked to be 7 mm.  
5. Blackish with an almost dark brown shine on its gastor.
6. Can't see any mandibles, head is roughly the same size as thorax maybe a little smaller.  
7. Anything else distinctive - Tons of brood!
8. Nest description - Tough to say because I was digging but pretty sure it was a volcano shaped nest.  

9. Nuptial flight time and date - N/A

Also, a few questions.  I have it in a test tube set up connected to a small bead container out world.  Wondering if this set up will suffice for some time.  She has around 8-10 workers and a bunch of brood.  Love to hear some suggestions.  Plan on leaving it alone for a while because the stress of relocating it.  Thanks!

By location collected, (number 1.) they mean on the map.
As in, region you live, in order to narrow down species.. I see its in the title..just saying lol

But maybe Crematogaster?

No, not Crematogaster. this may be way off, but I'm inclined to say possibly Pheidole or Tetramorium.


I accidentally froze all my ants

Looks like Tetramorium tsushimae. Wild colonies are usually teeming with queens, so they're not hard to scoop up. However, last year I captured a lot of wingless queens that were emerging from the nests during their nuptial flights and sadly they had a 100% failure rate. As such, you may not want to set your hopes too high.

Tetramorium immigrans or  Tetramorium tsushimae

 

T. tsushimae is smaller than T. immigrans. Tsushimae has queens around 6mm, while immigrans has queens around 8mm
