• Eristalis saxorum

  Blue-polished Drone Fly

  Eristalis saxorum is an uncommon species of syrphid fly (hoverfly) native to eastern North America. Adults are flower visitors, obtaining nectar and pollen from blossoms. The species exhibits typical drone fly characteristics, including bee-mimicry and hovering flight behavior. Larvae are presumed to be of the rat-tailed type, though they have not been formally identified for this species. The species is active from mid-March through late October, with adults overwintering in sheltered locations such as cave entrances.
