Annotation	An analysis of the ecophysiological aspects of overwintering in nine gerromorphan species is presented. All nine species avoid ice formation by means of more or less extensive supercooling of their body fluids. There is a tight correlation between supercooling capacity and lower lethal temperature. The majority of species studied overwinter only as adults, whereas Velia caprai Tamanini, 1947 can overwinter either in the adult or egg stage. The supercooling capacity of V. caprai adults is insufficient to prevent the risk of lethal freezing. Winter survival in this species is assured by extensive supercooling and highly cold-tolerant overwintering eggs.
