The effects of temperature and photoperiod were investigated in the laboratory. Time of eclosion was not affected by the photoperiod to which larvipositing females were subjected, but was affected by temperature. Eclosion was limited to the range 18-32ï¿½ C and was stimulated by change in temperature. Even a small change caused a response, and the rate of eclosion appeared to be related to the rate of temperature change. In nature, normal diurnal temperature changes would therefore result in apparent rhythms of eclosion, the pattern being bimodal in summer when mid-day temperatures are above the upper limit and unimodal in winter.
