Tsetse Fly

Vector of African sleeping sickness (trypanosomiasis). Unlike most flies, females give live birth to a single large larva. Both sexes are obligate blood-feeders.

💡

Did You Know?

The tsetse fly is unique among insects — it gives birth to live young. The female nourishes a single larva internally with a milk-like substance, similar to mammalian lactation.

Big-headed Fly

A small fly with an enormously enlarged, almost entirely eye-covered spherical head. It hovers in vegetation searching for leafhopper hosts in which to parasitize.

💡

Did You Know?

Its enormous eyes give it near-360-degree vision, allowing it to spot leafhoppers from any angle while hovering.
