& Sand Flies) (Contact) Please

Images & underlined links to view: Psychodidae. -- The moth flies
and sand flies have abundant
scales on their wings. They are small
to very tiny insects with a large number of hairs on their bodies. When at rest adults may hold their wings
roof like over the body. The
habitat is in moist shady areas but can also be found in drainages or
sewers. Adults may occur in bathrooms
that they enter via sink drains.
Larvae inhabit decaying vegetable matter, moss, mud or water. There are
some medically important species that are vectors of various fevers, such as Leishmania, Pappataci fever,
Kala-azar
and Oroya fever,
especially in tropical regions.
Service (2008) reported that there are almost 1,000 species in six
genera. Those that draw blood from
vertebrates are in the genera Phlebotomus,
Lutzomyia and Sergentomyia. Phelobotomus
species are absent from the Americas but range in parts of Africa and
Asia. They typically are active in
drier savannas. Lutzomyia are restricted to the Americas
where they are abundant in the forests of Central and South America. Sergentomyia
species also are not found in the Americas but rather Central Africa and
Asia. However, they do not generally
encounter humans and are not vectors.
Service (2008) listed the most medically important species are Phelebotomus papatasi, P.
sergenti, P. argentipes, P. ariasi, P. perniciousus and Lutzomyia longipalpis and L. flaviscutellata. = = = = = = = = = = = = = = = = = = = = Key References:
