Hoverfly (flower fly), likely a drone fly
Eristalis tenax
- Order & Family
- Diptera; Syrphidae
- Size
- Typically 11–14 mm long; this specimen appears roughly 12–14 mm.
Natural Habitat
Gardens, meadows, woodland edges, and other flower-rich habitats worldwide, especially near water or moist soil.
Diet & Feeding
Adults feed mainly on nectar and pollen, visiting flowers for energy and reproduction. Larvae live in organically rich, stagnant water and filter-feed on microorganisms and decaying material.
Behavior Patterns
Adults hover conspicuously, bask, and mimic honey bees, though they cannot sting. Females lay eggs near polluted or stagnant water; larvae are aquatic “rat-tailed maggots.”
Risks & Benefits
Harmless to people and not capable of stinging; occasional contact with food is mainly a sanitation concern. Adults are important pollinators, and larvae help decompose organic matter in water.
