Common Drone Fly

<em>Eristalis tenax</em>, the common drone fly, is a hoverfly in the family Syrphidae with a broad global distribution spanning Europe, Africa, North America, and South America, including records from South Africa, five European countries, the United States, and Chile. This species typically inhabits a wide variety of terrestrial and freshwater habitats, from urban gardens and agricultural landscapes to woodland edges and wetlands. The common drone fly is one of the most effective mimics of the honey bee, a resemblance that offers protection from predators. Adults are frequently observed visiting flowers to feed on nectar and pollen, making them important pollinators in many ecosystems. Larvae, known as rat-tailed maggots, are aquatic and typically develop in stagnant, organically enriched water bodies such as sewage drains, manure pools, and polluted ponds, where they breathe through an elongated, tube-like siphon. <em>Eristalis tenax</em> is assessed as Least Concern, with stable and widespread populations. It is regarded as both an ecological indicator species and a valuable contributor to pollination services.
