Macro
Invertebrates of the Red River
Midges
Order-Diptera
Family- Chironomidae
Midges look like mosquitoes but they do not bite. The
larvae are about a half and inch long and have a curved
body. They can be red, yellow, green, or white in color.
The red larvae are also called bloodworms. The larvae
move with a squirming motion. They have one pair of
legs below the head and one pair at the end of their
body. They can be found clinging to debris in the water.
Midges play an important role in the ecosystem of a
river. They are a source of food for fish and waterfowl
and they are involved in recycling organic wastes. Large
numbers of midges can indicate a large amount of organic
material in the water.
