Bees flies are generally stout-bodied, hairy flies that, because of their behavior - they are often found on flowers - and appearance, remind one of bees. Indeed, they are important pollinators. Bee flies usually fly close to the ground and can often be found resting on the bare ground. Sometimes they can be seen hovering the holes of ground-nesting bees. Bee fly larvae (juveniles) are parasitic on the young of various other insects. Some are parasitic on ground-nesting bees.
