black flies

Tiny bloodsucking pests

Black flies are small biting insects that swarm near running water, where they breed.

They're a notorious pest in wooded and mountainous regions, especially in late spring and early summer.

Their bites can cause intense itching and swelling.

In parts of Canada and the northern United States, black fly season is a dreaded annual event: The black flies were so thick we couldn't stay outside.
