Bee Fly

A fuzzy bee mimic with a long fixed proboscis used for hovering in front of flowers to drink nectar. Despite its innocent appearance, larvae are parasites of solitary bee nests.

💡

Did You Know?

Bee flies are aerial bombers — females flick their eggs into the entrance holes of ground-nesting bee burrows while hovering, never landing.

Parasitic Bee Fly

A medium-sized tachinid fly that parasitizes armyworm caterpillars and other crop pest larvae. It is found across multiple continents.

💡

Did You Know?

Females deposit multiple larvae on a single caterpillar but only one typically survives to maturity.
