In the spring, Winnipeg usually receives large amounts of rain that revives the prairie landscape from its dormant state. Winnipeg has 38 species of mosquitoes, and each species has a particular biology and behaviour. These species can occur at different times during the season or at different times during the day. Adult mosquitoes are small, thin bodied flies. They are called biting flies because they need blood to produce eggs.
Mosquitoes have a long thin mouth part called a proboscis with which they suck blood.
Only the female needs blood. You can determine the females by looking at the antennae. Males have very fuzzy antennae while the females antennae have only a few hairs. Adult mosquito Larvae Larvae are the young stages of the well-known adult mosquitoes. Larvae are often called wrigglers.
