Hoverfly (flower fly), likely a drone fly
Eristalis tenax
- Order & Family
- Diptera, Syrphidae
- Size
- Typically 10–14 mm long.
Natural Habitat
Flower-rich gardens, meadows, woodland edges, and other sunny habitats worldwide, especially near water where larvae develop.
Diet & Feeding
Adults feed on nectar and pollen, making them effective pollinators. Larvae consume organic material in stagnant water and filter-feed on microorganisms.
Behavior Patterns
Adults hover, bask, and visit many flowers; their bee-like appearance is defensive mimicry. Females lay eggs near nutrient-rich, polluted standing water, and larvae develop as aquatic rat-tailed maggots.
Risks & Benefits
Harmless to people and unable to sting; occasional larval contact with wounds is exceptionally rare. Adults provide valuable pollination, while larvae help decompose organic matter.
