Antarctic flies protect fragile eggs with 'antifreeze'
The good thing about the short Antarctic summer is it's a lot like a Midwest winter.
But for wingless flies, that's also the bad thing about Antarctic summers. The flies and their eggs must contend with an unpredictable pattern of alternating mild and bitterly cold days.
University of Cincinnati biologist Joshua Benoit traveled to this land of the Midnight Sun to learn how Antarctica's only true insect can survive constant freezing and thawing. He found that the midges have surprising adaptations for life wintry realm.
Benoit and his students presented their findings in January at the Society for Integrative and Comparative Biology conference in Tampa, Florida.
At some point in their evolution the little midge lost their wings -- possibly to cope with notorious Antarctic winds. Since they eat abundant algae and never travel far from where they're hatched the flies don't need to fly.
