Deer fly
Deer fly
Deer fly (Chrysops spp.), pronounced /ˈdɪər flaɪ/, is a common name for any member of the Chrysops genus of biting flies in the family Tabanidae. The etymology of the term "deer fly" is not definitively known, but it is likely derived from the fact that these insects are often found around deer, which they frequently bite.
Description
Deer flies are small to medium-sized flies, typically 6–10 mm in length. They are known for their distinctive patterned wings and brightly colored eyes. The females of most species are blood-feeding, while the males feed primarily on nectar.
Behavior
Deer flies are often found in damp environments, such as wetlands or forests. They are active during the day, particularly in hot, sunny conditions. Female deer flies feed on the blood of various mammals, including humans, to obtain the protein necessary for egg production.
Life Cycle
The life cycle of a deer fly includes four stages: egg, larva, pupa, and adult. The female lays her eggs in clusters on vegetation near water. The larvae hatch and drop into the water or moist soil, where they feed on organic matter and small organisms. After several molts, the larvae pupate and then emerge as adults.
Medical Significance
Deer flies are vectors for several diseases, including Tularemia and Loa loa filariasis. Their bites can also cause allergic reactions in some individuals.
Prevention and Control
Prevention of deer fly bites involves the use of insect repellents and protective clothing. Control measures include habitat modification and the use of traps.
