I know there is a mating flight thread already, but I thought we could get a bit more specific than just "North America." These would be flights occurring within the USA. I thought I would start with where I live, Michigan:
April: Prenolepis imparis
June: Camponotus, Formica
July: Formica, Lasius, Tetramorium, Pheidole
August: Lasius, Formica, Pheidole, Crematogaster
Any Michigan anters, please feel free to correct me if I am wrong. Also, this thread is open to other states as well, so anters in other states can put the nuptial flight times for genera in their home states as well.
