Snipe Fly

A slender, long-legged fly often seen perched head-down on a sunny tree trunk or fence post, patiently watching for smaller insects to ambush. Its tapered, wasp-like abdomen and habit of resting motionless with legs splayed give it a distinctive, almost sentry-like posture in woodland clearings.

Screwworm Fly

Screwworm Fly

A metallic blue-green blowfly whose larvae are unusual among maggots for feeding on living tissue rather than carrion, drawn to even small open wounds on warm-blooded animals. The species has been the target of one of the most successful large-scale insect eradication campaigns in history across much of North America.

Fruit Fly (Mediterranean)

Fruit Fly (Mediterranean)

A small but strikingly patterned fly with mottled, banded wings held out to the sides in a fan and a body dotted with silvery spots, best known for larvae that tunnel through ripening fruit. Native to sub-Saharan Africa, it has spread with human trade to become one of the most widely recognized fruit-infesting insects in the world.
