Abstract: In order to investigate the respective roles of photoperiod and temperature in seasonal regulation of the life cycle, experiments were undertaken to measure the rate of growth of dragonfly larvae when maintained to emergence under constant conditions of light and temperature. Eight experimental conditions were used: two photoperiods (11 and 14 hours) at each of four temperatures (15, 20, 25, and 30 °C). The effects of light could thus be determined when photoperiod was the variable and temperature was held constant; the effects of temperature could be analyzed where it was the variable and photoperiod was constant. The final-instar larvae were collected from September, 1969, to May, 1970, and were subjected to the experimental conditions in order to observe the effect of seasonal variations in relation to photoperiod and temperature.
