Of the 80 mosquito species found in Florida, APPROXIMATELY 30 species may be found in Dixie County, and to the trained eye, each one looks as different as a poodle and a doberman. Adult mosquitoes vary widely in size, ranging from about 1/8 inch to about 1-1/2 inches.
Adult females usually live about a week or two, while adult males live only long enough to mate, about two to four days. Only female mosquitoes bite. They need the protein in blood to produce eggs.
A female can produce as many as 250 eggs from one bloodmeal. After the eggs are laid, they may hatch in a couple of days or it may be months before they hatch.
The larva, or wriggler, emerges from the egg and grows from 1/16″ to 1/4″ in length in four to ten days, depending on the temperature of the water they grow in.
The next stage is the pupa, or tumbler. This stage lasts only about two days. During this time the mosquito transforms from the aquatic larva into the flying adult. The pupa does not feed.
