Horse Stomach Bot Fly

A bee-like fly that glues eggs to horse leg hairs where they are ingested during grooming. Larvae attach to the stomach lining and develop for months before passing out.

Larvae survive the acidic horse stomach by secreting a protective alkaline buffer around themselves.

Phantom Crane Fly

A delicate fly with swollen black and white banded tarsi that acts as a tiny parachute, allowing it to float effortlessly on air currents.

💡

Did You Know?
