1. Location of collection: Horsham a suburb just outside of Philadlephia.
2. Date of collection: April 9th, 2017.
3. Habitat of collection: The ants were found on reddish/orange, clay soil. The patch of the mound the ants were found on faces the SW direction, and the ants were seen in full sunlight.
4. Length: First worker: ~5 mm, Second Worker: ~2-3 mm
5. Coloration: The first worker looks to be a reddish/brownish warm hue with slightly lighter legs. The second was almost entirely pitch black but its gastric hairs seemed to appear fairly reflective at times, making it look slightly silverish/grey.
6. Distinguishing characteristics: Nothing in particular. I would describe the first one as resembling a large, lighter tetramorium worker and the second as resembling a very, very small you Camponotus pennsylvanicus worker.
7. Anything else distinctive? Was on the lookout (or "smellout" 
) for a particular odor out of the second, smaller worker. My brother claimed he smelled something, but I didn't.
8. Nest description: Holes in the slightly damp, dense dirt where they were caught.
9. Photos. Unfortunately, my iPhone didn't cooperate and I didn't get great photos of the ants. I did, however, manage to get a pretty good video if it helps:
Note: I know the first, larger one is either Myrmica or Aphaenogaster, and I understand both of these are notoriously difficult to properly identify. I'm also fairly sure the second is Tapinoma, probably Tapinoma sessile, but I had no idea they were so little.
Thanks,
Void.
