A couple weeks ago I was looking around for ants at 8pm and I saw a massive Camponotus pennsylvanicus colony (hundreds of workers on the surface) acting strange, they had mant super long trails full of ants and walking back to the nest I saw them swarming at the nest but no food, no predators, and no alates to be seen so I was curious if they were attempting to fly. I couldn't stay for long as I was already on my way out but maybe I can come back soon and look for founding queens in that area. So all i want to know is if they were preparing to fly or something else also I didn't rain recently and and if it did it was very light.
Were they digging and making the nest entrance wider? Because that is what a lot of ant species do when they’re about have a nuptial flight. Just saying, Camponotus can also have flights in the morning or even midday, but normally they have their nuptial flights in the evening. I found my Camponotus queens at 4:30 pm. Another thing to consider is their circadian rhythms, Camponotus is a species that is more active during the evening and night, so it could be that they were just doing their thing.
Currently keeping:
1x Formica subsericea, 35-40 workers + maybe eggs *New* 2x Camponotus nova, one has only larva
1x Crematogaster cerasi, All workers is ded 
*extreme internal screaming* 1x Myrmica ruba sp around 10 workers + pupa
*New* 1x Temnothorax curvispinosus, 101 or something worker + 3 or 4 royal mom ants + pile of white ant worms
*As you watch your ants march, remember that every thing begins with a small step and continued by diligence and shared dreams* -A.T (which is Me)
Sadly due to unforeseen consequences, I will soon be giving away my colonies (I will miss them though 
)
