Drone Fly (likely a Spotted-eyed Drone Fly)

Natural Habitat

Found near water sources, marshes, sewage lagoons, and gardens with flowers.

Diet & Feeding

Adults feed on nectar and pollen from flowers; larvae (known as rat-tailed maggots) feed on organic matter and bacteria in stagnant or polluted water.

Behavior Patterns

They are mimics of honey bees to avoid predators. Known for 'hovering' mid-air before darting away. The larvae have a long posterior siphon (tail) used for breathing while submerged in water.

Risks & Benefits

Benefits: Important pollinators for various plants. Risks: Larvae can rarely cause accidental intestinal myiasis in humans if contaminated water is ingested, but generally considered harmless and beneficial to the ecosystem as decomposers and pollinators.
