Life Span

Male mosquitoes have an average life span of 10 days. Female mosquitoes can live for up to 100 days.

Mouth Physiology

Male mosquitoes have small mouth parts for drinking. Female mosquitoes have a proboscis that can pierce into the skin.

Antennae Physiology

Male mosquitoes have longer feathery antennae hairs that help in finding a mate. Female mosquitoes have short hairs on their antennae.


Male mosquitoes drink plant nectar. Female mosquitoes also drink plant nectar, but need to drink animal blood when it is time to lay eggs.


Female mosquitoes of certain species can carry diseases such encephalitis and malaria, which are transmitted to humans when the mosquito takes blood. Use an insect repellent containing DEET and clothing that adequately covers your skin to reduce the chances of being bitten.
