Notes on Biology. Specimens have been taken in Lindgren funnels, Malaise traps, and by hand. A single specimen was extracted from a nest of Bombus centralis Cresson, 1864 .

Additional Remarks. This seems to be the most frequently collected of all Antherophagus species in Montana, and is the species known from the greatest number of counties ( Fig. 21 ). It has been collected both in the mountainous western portion of the state and the flatter eastern portion near the North Dakota border. However, we are still missing records from many counties in Montana, especially in the central and eastern portions ( Fig. 21 ).
