Horse Fly

A large, stout fly with huge iridescent compound eyes that display rainbow patterns. Only females bite, using scissor-like mouthparts to slash skin and lap up blood.

💡

Did You Know?

Horse fly eyes display stunning iridescent bands of color created by structural interference patterns, and scientists have used their anti-reflective eye structure to design better solar panels.

Banana Stalk Fly

A slender long-legged fly from Australia whose body size depends on larval nutrition. Larger males pass on a size advantage to offspring even through a non-genetic pathway.
