Certain amphibians (i.e. tree frogs) have a "natural anti-freeze" compound in their blood. This allows them to hibernate through 20°F freezes - without any cell walls rupturing due to ice spikes - and just thaw back out in the spring. Perhaps parent comment was wondering if a special subspecies of mosquito or mutation was capable of the same?
