Moth fly

The Psychodidae are small true flies (Diptera) with short, hairy bodies and wings giving them a "furry" moth-like appearance, hence their common name moth flies.

Description

Moth flies are classified as Nematocera and are small (<2 mm). The adults have long antennae and the wings are leaf-shaped, either slender or broad, with the most elementary wing venation of any Diptera, having little more than a series of parallel veins without crossveins. Adult Psychodidae are typically nocturnal, though they orient themselves around lights and may appear to be attracted to light.

Sand flies

The subfamily Phlebotominae includes many blood-feeding species; they are inhabitants of more arid regions and are often called sand flies outside the United States where sand flies are distantly related Nematocera of the Ceratopogonidae. This subfamily is sometimes treated as a separate family Phlebotomidae; the type genus is Phlebotomus. Phlebotominae are a very important group medically, transmitting various tropical diseases, but most importantly kala azar leishmaniasis. Phlebotomus species are also vectors for bartonellosis, verruga peruana, pappataci fever, an arbovirus caused by sandfly fever viruses such as Naples and Sicilian strains, which are members of the genus Phlebovirus (family Bunyaviridae), which also includes the closely related Toscana virus.
