Sandflies
Sandflies (pronunciation: /ˈsan(d)ˌflī/), also known as sand fleas or sandfleas, are a group of about 700 species of small biting insects that are found worldwide. They are part of the family Psychodidae.
Etymology
The term "sandfly" is a compound of the words "sand" and "fly", which is a direct reference to the insect's habitat and behavior. The term is used to refer to various species of small biting flies that are found in sandy areas.
Description
Sandflies are small, usually between 1 and 3 mm in length. They have a grey or brown body, and their wings are often held in a V-shape over their body when at rest. The females of many species are hematophagous, meaning they feed on the blood of vertebrates, including humans.
Behavior and Habitat
Sandflies are most active during the twilight hours and at night. They are found in a variety of habitats, but are most common in sandy areas, such as beaches and deserts. They are also found in forested areas and in urban environments.
Health Impact
Sandflies are vectors for several diseases, including Leishmaniasis, Sandfly fever, and Pappataci fever. These diseases are transmitted to humans through the bite of an infected sandfly.
