I have been keeping ants for about 2-3 years. I have such a biodiversity of ants up here!!! It's unbelieveable!!!! P. imparis is my favorite species!!! I have i think 8 colonies. Waiting for this years flight. I'm currently keeping formica (like 5 different types), a slavemaker ant colony that i boosted from wild pupa; and they just came out of hybernation and i fed her my protein food so i hope she lays, she is a slavemaker of formica, lasius neoniger, lasius flavus, componotus penn, some smaller camponotus, lasius alienous, acorn ants, pheidole, trying to start a myrmica queen, tetremorium, and brachomerex. I think there is more but can't remember! haha! The only species i can never catch is aphenogaster!!! Last year i saw one on my schools roof from the library!! Then another landed on our car as we were driving! Oh i also am starting a citronella ant colony (i think lasius claviger).
