Eristalis species, likely *Eristalis tenax*
- Order & Family
- Diptera; Syrphidae
- Size
- About 10–15 mm (0.4–0.6 in) long.
Natural Habitat
Gardens, meadows, forest edges, and other flower-rich habitats worldwide. Adults commonly visit composite flowers for nectar and pollen.
Diet & Feeding
Adults feed on nectar and pollen; larvae of *Eristalis tenax* develop in nutrient-rich, stagnant water and filter-feed on microorganisms and organic matter.
Behavior Patterns
Adults hover skillfully, bask, and often mimic bees or wasps for protection. They are important pollinators; larvae are known as rat-tailed maggots because of their breathing siphon.
Risks & Benefits
Harmless to humans and lacking a sting; occasional accidental contact is benign. Adults provide valuable pollination, while larvae help decompose organic material in water.
