Aedes albopictus
Aedes albopictus (Stegomyia albopicta), from the mosquito (Culicidae) family, also known as (Asian) tiger mosquito or 'forest mosquito', is a mosquito native to the tropical and subtropical areas of Southeast Asia; however, in the past couple of decades this species has invaded many countries throughout the world through the transport of goods and increasing international travel. It is characterized by its black and white striped legs, and small black and white striped body.This mosquito has become a significant pest in many communities because it closely associates with humans (rather than living in wetlands), and typically flies and feeds in the daytime in addition to at dusk and dawn. The insect is called a tiger mosquito because its striped appearance is similar to that of a tiger. Aedes albopictus is an epidemiologically important vector for the transmission of many viral pathogens, including the Yellow fever virus, dengue fever and Chikungunya fever, as well as several filarial nematodes such as Dirofilaria immitis.
