I believe Miles keeps them. His YT channel is The Ant Network. From what I understand, their interest in food varies, so they must have constantly shifting food sources. This is of hunteri, and being in CO, yours is likely invidia, but they are similar enough that it likely still applies. In the wild, I have seen them nest in sandy soils, that are near a body of water. hunteri lays only after hibernation, and I would assume invidia is the same. The queens are semiclaustral, and I believe Miles recommended putting dirt or bark in the test tube. that's all I know, as I unfortunately have never been able to find a queen.
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).
