A fast-flying bee mimic, the fuzzy and buzzing Laphria astur is a fly that sometimes sends people needlessly dodging for cover.

Agile airborne predators, Robber Flies are quick, large, and fierce when it comes to capturing a meal. Robber Flies 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 Robber Fly darts to it, intercepts it, and quickly kills it, stealing it out of the sky. The meal is eaten on the ground or in a nearby tree.

Laphria astur has the overall appearance of a bumble bee. Misidentifying the Robber Fly as a large, stinging bee is common. It is hairy, black, and yellow with brown-tinted wings. The flight speed of the Robber Fly is faster than a bee though, and its buzzing noise is a bit louder. In a quick second, such small distinctions can be lost on people worried about getting stung.

Robber Flies have short antennae and slender bodies that taper at the tip of the abdomen. A long beak at the front of the face is used for spearing insects. If you hear one, try to follow it to its resting perch. Many Robber Flies allow people get a closer look before jetting off to a more obscure lookout point. This particular species resides in the northwestern states and provinces of the continent.©InsectIdentification.org

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the Robber Fly - L. astur may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America. States/Territories shown above are a general indicator of areas inhabited by the Robber Fly - L. astur. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
