Hello, I'm in Denver Colorado and I recently caught some pogonomyrmex. When I posted pictures in the past they were ID as occidentalis but these ones seem larger this year, I thought at first they were majors and even dumped a few out because they didn't look "right" until I compared them to worker. Is there a way to differentiate between occidentalis, rugosus, and barbatus? I looked at antswiki and it said occidentalis isn't out until August and I found these July 18. Both rugosus and barbatus are flying in July according to anywiki. Of course with global warming these times are changing and maybe this year's occidentalis are just a little bigger? If anyone has any easy ways to differentiate between the 3 let me know!

don't trust antwiki on everything. Occidentalis fly during June all the time, it isn't because of global warming.

Barbatus is very chunky, way beefier than occidentalis. Rugosus should be easily ruled out based on color; they are brown, the other species in Colorado are red/orange.

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).
