Greenhead Horse Fly

A coastal salt marsh horse fly with bright green eyes. It is the most abundant biting fly along the Atlantic coast of North America.

💡

Did You Know?

Greenheads are so abundant in some coastal areas that they limit beach recreation in summer.

Flesh Fly

A large gray fly with three black longitudinal stripes on the thorax and a checkered abdomen. Unlike most flies, females give birth to live larvae rather than laying eggs.

💡

Did You Know?

Flesh flies are larviparous, depositing live first-instar maggots directly onto food sources, giving their offspring a developmental head start over egg-laying competitors.
