Sand Fly Bites

The Sand Fly

Sand flies are about 1/8 of an inch long, and have hairy, brownish-gray wings, which they hold above their bodies in a “V” shape. In the U.S., they are found primarily in the southern states. They breed in places with a lot of moisture, such as decaying plants, moss, and mud. The larvae look like worms. They are most active between dusk and dawn. Sand flies eat nectar and sap, but females also feed on the blood of animals and humans. They live mainly in tropical and subtropical climates.

Sand Fly Bites

Sand flies are tiny and quiet, so you may not notice them before they bite. The bite can be painful and may cause red bumps and blisters. Sand flies transmit diseases to animals and humans, including a parasitic disease called leishmaniasis.
