- Complete metamorphosis (egg, larva, pupa and adult).
- Egg- laid single or in groups on water services that will be covered with water
- Larva- Develop in water feeding on organic materials; different species live in different type of water, breathe air by coming to the service and some attach to plants and are very active.
- Pupa- Very active but does not feed; lasts 1to several days and rises to the surface when ready to emerge.
- Adult- Male emerges first. Female must have a blood meal to produce fertile eggs.
(a) Anopheles- Eggs laid singly usually among aquatic plants. Each egg floats and larva lie parallel to water surface.
(b) Mansonia- Eggs laid in rafts; Larvae and pupa insert air tube into aquatic plants to obtain air. Pupa remain attached until ready to emerge and development requires several months.
(c) Culex- Eggs laid in rafts and some in artificial containers.
