Indian Sand Fly

A tiny, hairy fly with a distinctive humpbacked appearance and large, upturned wings held erect at rest. It is the primary vector of visceral leishmaniasis (kala-azar) in the Indian subcontinent.

💡

Did You Know?

Indoor residual spraying with DDT once nearly eliminated kala-azar from India, but the disease resurged after spraying campaigns ended.

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.
