Here are some interesting facts about mosquitoes. More than 3,500 species of mosquitoes exist in the world, including at least 200 different species in the U.S. Female mosquitoes lay their eggs in water, where the larval and pupal stages occur.
The eggs of mosquitoes are long and blackish in color. When they hatch, the larvae are known as "wigglers" because they swim in s-shaped movements. In the pupal stage, the head and thorax are merged as one and the abdomen curves underneath like a comma. At this stage, mosquitoes are known as "tumblers" for the way they move or swim in water.
Adult mosquitoes are small, flying insects less than 1/2" in length with slim bodies and long legs. Their thin bodies have three segments: head, thorax and abdomen. Heads have compound eyes and segmented antennae for detecting host odors. The elongated stinger is used for sucking blood from the host, whether human or animal. Their painful bites can leave lumps on skin and spread disease.
