Mountain Prosimulium
An early-season black fly of cold mountain streams in North America. Larvae develop in small headwater streams during late winter and early spring.
Did You Know?
Adults emerge so early in spring that they are often the first biting flies encountered by hikers each year.
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.
