Large-tailed Aphideater
Eupeodes volucrisAlso known as Bird Hover Fly
Large-tailed aphideaters are nimble flower visitors that mimic yellowjackets to ward off predators while posing zero threat to humans. Female flies deposit single eggs directly into dense aphid colonies, unleashing voracious legless larvae that consume hundreds of crop pests before pupating. Adults display impressive aerial control, hovering motionless in midair before darting away in the blink of an eye.

Responsible observation
- Approach Slowly: Pause near blooming flowers and move gently to photograph adults while they hover motionless.

- Check Leaves: Look on the undersides of aphid-infested leaves to spot translucent, pale green larvae at work.
