wasp
Hoverfly
A slender, bee- or wasp-patterned fly known for its remarkable ability to hover motionless in midair before darting suddenly to a new flower.

Wax Moth
A plain grey-brown moth whose larvae tunnel through beeswax honeycomb, spinning silk webbing as they feed, making it a well-known pest of beekeeping operations.

A small, grayish-brown snout beetle with a long, curved rostrum, historically famous for its close feeding association with cotton flower buds and bolls.
beetle
Warble Fly
A furry, bee-mimicking fly that never lands on flowers or feeds as an adult, spending its brief life darting around grazing cattle to lay eggs on their legs and lower body. Herds sometimes react with sudden panicked runs, known as gadding, whenever a warble fly approaches.
