Dytiscus marginalis do not exist below certain elevations and are found in mountain lakes or ponds or in collections of melted snow. Adults hibernate under stones to avoid being frozen in the water during colder seasons. (Evans and Bellamy 1996) These beetles are active anywhere by the ice, where they exploite the oxygen bubbles that usually occur under ice along with dissolved oxygen.(Crowson 1981)
