通过野外观察和室内实验，以翅斑红鳞数为标准，研究了控制灰蝶幼虫期的季节性形态决定和延长的环境因子。幼虫期的光周期和温度条件以及蛹期的低温（5°C）预计将成为影响季节性形态确定的因素：实验室实验证实了这些影响。此外，在20°C短日照下，幼虫期延长，而在25°C短日照下，幼虫期延长与春季形态决定有明显的相关性，但相关系数为负，与蓼属和凤蝶属的情况形成鲜明对比。
Environmental factors controlling seasonal morph determination and extension of the larval stages inLycaena phlaeas daimiowere studied in field observations and laboratory experiments, using criteria based on the numbers of red scales in the wing spots. Photoperiod and temperature conditions applied during the larval period and a low-temperature (5°C) introduced in pupal period were expected to be factors affecting the seasonal morph determination: the effects were confirmed by laboratory experiments. Furthermore, the length of the larval period extended by exposure to short days at 20°C, but not at 25°C, were found to show a clear correlation with the spring morph determination, but the correlation coefficient was negative in marked contrast to the situation inPolygoniaandPapilio.
