Mosquito Biology

Life Cycle

Mosquitoes are a flying insect that belong to the Order Diptera and Family Culicidae. They undergo complete metamorphosis a process much like butterflies. Complete metamorphosis has 4 stages; egg, larva, pupa, and adult. Mosquitoes spend 3/4 of their life cycle in the water: egg, larva, and pupa stages. The last stage, the adult flying stage is spent terrestrially on land and in the air. 

Feeding Habits

Juvenile mosquitoes feed on nutrient particles in the water and adult flying mosquitoes feed on plant nectar and blood. Only female mosquitoes feed on blood, they need the nutrient rich blood to fuel the egg laying process. 


Mosquitoes are of great public health importance because it can transmit diseases. In Suffolk we are most concerned with West Nile Virus and Eastern Equine Encephalitis.
