B.melanopagus
B.melanopagus are easy to recognize with a bright orange abdomen. We remove more nests of these then any other bumble bee species. They often nest in bird houses using the old bird nest from a past year to nest in. We have found them nesting in the insulation in walls, in grass clipping piles, old mouse nests, several compost piles, and in the insulation of several water shut off boxes. They can be aggressive with defending their nest and will often attact people if they are standing to close to their nest.
