So I've caught some and uploaded here to get help identify them.

Ant 1.
size: ~ 1cm
color: black
caught: side walk near a pine tree

All of these are difficult to identify due to poor lighting, but few genera in North America get as big as 1cm other than Camponotus.

I would say Camponotus pennsylvanicus for ant 1, and either Camponotus
Americanus
or Camponotus castaneus for ant 2.

Ant 3 looks like Formica, but I would want better pictures to say with confidence.

The measurements seem a little off.

The first worker is Formica, although I would need a clear view of the details outlined in your other Formica colony ID to narrow down to the species.

Worker two is Formica pallidefulva.

Worker three is Camponotus, either C. novaeboracensis or C. nearcticus (possibly even C. subbarbatus). A view of the clypeus at the front of the head is necessary to distinguish the un-notched Camponotus subgenus from he notched Myrmentoma subgenus.
If you enjoy my expertise and identifications, please do not put wild populations at risk of disease by releasing pet colonies. We are responsible to give our pets the best care we can manage for the rest of their lives.

And after I just learned to tell Formica from Camponotus :lol: That's embarrassing. :oops:

Thank you, BleedingRaindrops and Batspiderfish.
Appreciate your time and effort.
I will try to take better pictures next time to capture the key features of identification.
BTW, do you have any recommendations? I would like to learn how to identify ant species at least my area.
