9. Nuptial flight time and date: I presume it was no more than a few hours earlier as I found 4 queens.
I'm not sure if this is Tetramorium caespitum or Aphaenogaster occidentalis. Based on the images from AntWiki, the only major difference I can see between the two is that T. caespitum has a slightly longer gaster, with more spaced out bands. Based on this fact, I'm leaning Tetramorium. However, I'm sure there is some more substantial difference between the two. Once I get some workers, I can sacrifice one so I can put it under a microscope and run through the keys.
