Can the Antarctic terrestrial midge, Eretmoptera murphyi, tolerate life in water?
1. Early‐season flooding and ice entrapment at sub‐zero temperatures pose significant challenges to any polar terrestrial invertebrate. 2. The chironomid midge, Eretmoptera murphyi , is native to the sub‐ A ntarctic island of S outh G eorgia and has been introduced to the maritime A ntarctic ( S ign...
