Stream floodplain disturbed in winter 2020-2021 by heavy equipment during stream restoration work. Large patches of bare ground, stands of exotic perennial grasses re-establishing, large patches of Chenopodium simplex and C. berlandieri with many ripe seeds, and patches of still-flowering Helianthus annuus and Sisymbrium loeselii. Early night, the first few hours after sunset. Smoky, wind calm varying to light breeze, partly cloudy, 75 F to 64 F.

This individual looks like a good match for P. aurifer, our only known native Polistes in Montana - the basal flagellomeres are mostly orange dorsally, unlike this puzzling individual found on the same site a month earlier. Unfortunately my photos of this individual are too fuzzy to count flagellomeres - but I would think this might be a male, since that would explain the choice of sleeping quarters.
