Only female mosquitoes feed on human/animal blood, while male mosquitoes feed on nectar.

Life cycle of mosquitoes

egg

Aedes - Aedes mosquitoes can resist drying for up to 6 months. Eggs are placed on the edge of the water line. Eggs are cigar-shaped.

Kulex - Eggs are tightly packed together to form a raft.

Anopheles mosquitoes - eggs placed separately. Anopheles eggs are quite unique because there are two floats on both sides of the eggs, which can float on the water.

Larva

At this stage, larvae must undergo four stages of molting, from 1 to 4 years old, in order to develop into pupae stage. It takes 4 to 10 days for the first instar larvae to develop into pupae.

pupa

During pupal stage, it does not need to be fed.

The pupal lasts about 1-3 days and then becomes an adult mosquito.

Adult

Most mosquitoes are self-bred and need blood meal to reproduce.

Morphological differences among three mosquitoes:

Aedes mosquitoes: black with white stripes on legs

Culex pipiens: brown, none

Anopheles maculata: brown, winged wings

Carrier of disease

Mosquito-borne diseases, such as Zhaika virus and dengue fever, are well known in Singapore. The carriers of these diseases are Aedes mosquitoes (Aedes aegypti, Aedes albopictus). Although Anopheles mosquitoes are the vector of malaria, and Culex mosquitoes are the vector of West Nile virus, Japanese encephalitis.

Different feeding times

It is well known that Aedes mosquitoes have been fed at dusk and dawn.

Culex mosquitoes feed all night.

Anopheles mosquitoes feed during sunset and sunrise
