It is okay to keep non native species if you find them in your area. Generally, if you are finding them, they are already established. This can be a touchy subject, but I find this to be the most reasonable argument.

	Hi there! I went on a 6 month or so hiatus, in part due, and in part cause of the death of my colonies. 
However, I went back to the Sierras, and restarted my collection, which is now as follows:
Aphaenogaster uinta, Camponotus vicinus, Camponotus modoc, Formica cf. aserva, Formica cf. micropthalma, Formica cf. manni, Formica subpolita, Formica cf. subaenescens, Lasius americanus, Manica invidia, Pogonomyrmex salinus, Pogonomyrmex sp. 1, Solenopsis validiuscula, & Solenopsis sp. 3 (new Sierra variant).
