About Eristalis saxorum (Wiedemann, 1830)
Eristalis saxorum (Wiedemann, 1830), commonly called the Blue-polished Drone Fly, is an uncommon species of syrphid fly located in the Eastern United States. Hoverflies, the common name for this group, get their name from their ability to stay nearly motionless while in flight. Adult hoverflies of this species are also referred to as flower flies, because they are commonly found around and on flowers, where they collect energy-giving nectar and protein-rich pollen. This species has rat-tailed larvae that are aquatic filter-feeders, though the specific larvae of Eristalis saxorum have not yet been identified. Very little is known about this uncommon species, and its flight period ranges from mid-March to late October.
