P. imparis, Pheidole and Lasius neoniger are my favorites. However only have 2 of those 3
On a side note, at the end of our driveway the woods are clear for a 30x10 patch, and about 3x10' of that is a flat sandy/rocky/loose soil area not covered in leaves (most of our lot is forest aside from a seasonal pond). This is where there are quite a few Lasius sp, and where C. americanus had previously had nests (not seeing it this year, though they hide entrances very well.) Now that I've been gone for over a week, I surveyed that area to check for flights, changes, etc. Today I noticed today three small hills about the size of quarters with *very* tiny light brown ants coming out. Going to see if I can get an ID as not sure if Monomorium, Pheidole, etc.
Other thing I noticed today is the Camponotus Myrmentoma colony residing in an enclosure outside has alates. Guessing overwintering as they typically fly in May.
