A fast-flying bee mimic, fuzzy and buzzing Laphria astur is a Robberfly that may have people needlessly dodging for cover.
Agile airborne predators, Robberflies are quick, large, fierce when it comes to capturing a meal. Robberflies eat other flying insects like beetles, bees, and flies. They sit still on leaves or branches, waiting for prey to fly nearby. Once a target is spotted, the Robberfly darts to it, intercepts it (usually in the air) and kills it. The meal is eaten on the ground or in a tree, not mid-air.
Laphria astur has the overall appearance of a bumble bee. The speed of flight of the Robberfly is faster though, and the buzzing noise they make is a bit louder. Robberflies have short antennae and slender bodies. Look for it in the northwestern states and provinces of the continent.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
