What Are Biting Flies?

Biting flies, also known as biting midges or no-see-ums, are small insects that belong to the family Ceratopogonidae. These flies are often less than 1mm in length and are difficult to see with the naked eye. Despite their tiny size, they can cause significant discomfort and irritation when they bite.

Causes of Biting Fly Bites

Biting flies are attracted to hosts for various reasons, including the carbon dioxide we exhale, body heat, and certain chemicals in our sweat. They use their sharp mouthparts to pierce the skin and inject saliva, which contains anticoagulants and other substances that help them feed on the host’s blood. The saliva can also cause an allergic reaction in some individuals, leading to itching and swelling.

Greenhead flies Greenish-black, 1/8 to 1/4 inch long, found in wetlands and marshes
