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. They occur in all kinds of standing water such as ditches, woodland pools, and unkept birdbaths. The larvae feed on algae and organic material. Only female mosquitoes need a blood meal, which they require to develop their eggs.
