No, this is Lasius aphidicola. They are supposedly easier to raise by a large margin than interjectus. The other species option would be speculiventris, but it does not seem to have the gaster pilosity of that species.

I've never caught one of these before, don't even know where to start. Found it on the porch while I was out looking for camponotus. Best pics I can get at the moment. 6 or 7mm.

Lasius interjectus, a social parasite.

I'll probably put her back where I found her tomorrow then. Thanks.

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).

yeah this one isn’t interjectus. Id guess that its speculiventris since they apparently fly quite early in the year.

Indeed. Myself and another keeper from the northeast learned that speculiventris actually have their main flights in late June/Early July. This hardly, if at all, overlaps with aphidicola

Yeah, definitely should be L. aphidicola.
