Realized I never gave a proper introduction! I'm from Southern California where we primarily have Acromyrmex versicolor. We're supposed to also have Cyphomyrmex and Trachymyrmex but I don't think I've heard of anyone finding them. No Atta's, except maybe to the extreme east, basically in Arizona.
I'm fairly experienced with keeping non-fungus growing ants. I'm also professionally and unprofessionally (rather, non-professionally

) an engineer, geologist, biologist, botanist, tinkerer, and annoyance (just kidding, I hope) so I love trying different methods and building new ideas.
