I just checked to see when you got this queen, and since it was 2 months ago, a fast growing genus like Dorymyrmex should at least have larvae by now. Maybe try a heating cable, and if there is no progress, I'd say just leave in a drawer and forget about her, and maybe she'll decide to get workers. That's what I do for any seemingly infertile queens.
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).
