A study of the life cycle and behavior of the Stratiomys normula unilimbata Loew. in a pond in Itasca State Pork, Minnesota, showed that larvae overwinter in the bottom of the shallow pond and emerge in July. Some of the mortality factors are suggested, including the ichneumonid parasite, Ceratophygadeuon sp., reared from the larva and drowning of the pupa following a sudden increase in water level. Drastic reduction of the water level would also result in larval mortality.
