Eggs of the predaceous water beetle Dytiscus alaskanus were incubated in the laboratory at 10, 15, 20, 25 and 30°C. All measures of rate of development showed a significant linear regression with temperature. Mortality rates showed no significant regression with temperature. Data for this species were compared with similar data for D. marginalis and results discussed with reference to the climate each experiences.
