Antarctic Midge

Belgica antarctica

Also known as Wingless Antarctic Midge

Antarctic midges spend two full years as larvae buried beneath snow and moss, feeding on algae, decaying organic matter, and penguin guano before emerging for just a few days of adult life. Lacking wings, they crawl along exposed rocks and coastal vegetation, an adaptation that prevents them from being blown into the ocean by fierce polar winds. They survive freezing, extreme dehydration, and high ultraviolet exposure by drying out their tissues and suspending metabolic activity during harsh winter months.
