Identification
T1-T2 yellow and T3-T4 red as in symmpatric flavifrons. In centralis the hue of yellow is more golden and black hairs on the thorax anteriorly are lacking or inconspicuous (vs. extensive in many flavifrons resulting in a more or less grizzled appearance). In some the red of T3-T4 is faded so that T3-T4 appear nearly yellow and confusion with fervidus is possible (note yellow facial hairs of centralis).

With experience the shorter malar space of centralis can be seen in both sexes.
Range
Abundant in the Great Basin and mountains to the south, including relatively low elevations, whereas the similar B. flavifrons is found in this region mostly in high mountains.
Food
