Veromessor andrei: About 15 workers, $60
Two formica argentea colonies, they have 3-8 workers each colony
Camponotus maritimus: 2 workers
Two formica+camponotus colonies: $60 total, must be purchased together.
I prefer to sell locally, pickup is in the San Francisco Bay area. Will knock off a few bucks for local pickup, otherwise shipping is $10. I cannot offer live arrival guarantee, but I always package the ants securely and have never had problems.
