How do you identify an Anopheles larvae?
Culex and Anopheles are yellow-ish, but you can identify them by observing their resting position. Anopheles mosquitoes have a ~45 degree angle, while Culex stay parallel to the surface. Microscopically, look for antena morphology and wings. To identify instars, just look at the size and the color of the larvae.
What do mosquito larvae look like?
Larvae. Within a week, the eggs hatch in water, becoming mosquito larvae called “wigglers.” A mosquito larva looks like a small hairy worm, less than a 1/4-inch long. It has a hard round head, a soft body, an abdomen with 10 segments and a siphon tube at the tip of its abdomen.

What are the characteristics of Anopheles mosquito?
Like all mosquitoes, adult Anopheles species have slender bodies with three sections: head, thorax and abdomen. The head is specialized for acquiring sensory information and for feeding. It contains the eyes and a pair of long, many-segmented antennae.
Where do Anopheles mosquitoes breed?
During the rainy season, rain pools and water bodies created by the seasonal Gash River serve as the main breeding sites. In the dry season, irrigation canals, seepage from water pipes, neglected wells, artificial containers, and man-made ditches serve as the main breeding sites.
What is the life cycle of Anopheles mosquito?
Life Stages Like all mosquitoes, anopheles mosquitoes go through four stages in their life cycle: egg, larva, pupa, and adult. The first three stages are aquatic and last 7-14 days, depending on the species and the ambient temperature. The biting female Anopheles mosquito may carry malaria.
Are mosquito larvae harmful?
Thankfully, mosquito larvae don’t bite people or animals, and even if ingested by animals drinking the water they’re living in, don’t typically cause harm to the animal. The life stage that harms humans and animals appears to only be the adult stage.

Larvae: The larvae of Culex pilosus have a broad head and long antennae with a large tuft at the ends. On the ventral side of the larval head, an oval gill is inserted at the base of the antennae (Carpenter and LaCasse 1955). They have an upcurved siphon and a curved preapical spine at the end of the siphon.
