Drone Fly

A large hoverfly that is an excellent mimic of the honey bee, complete with similar coloring and buzzing flight. Its aquatic larva is known as a rat-tailed maggot due to its long breathing siphon.

💡

Did You Know?

The rat-tailed maggot larva can breathe in heavily polluted water by extending its telescoping tail siphon up to 10 centimeters to reach the surface air.

Sweat Fly

A small dark fly attracted to perspiration on humans and livestock. It forms dense head-circling swarms in summer that can be extremely annoying.
