控制季节性翅膀二型性的东方的蟋蟀Gryllotalpa orientalis Brumeister（1839）从日本西部的湿地栖息地。长翅型（LW）出现在6月中旬至9月，而短翅型（SW）出现在9月至6月中旬。个体在成虫或幼虫阶段越冬。翅膀形态的季节性变化与越冬阶段有关。5月孵化的个体在9 - 10月成为SW成虫，然后越冬，而6月和7月孵化的个体作为幼虫越冬，并在次年6月成为LW成虫。这两个变种的生活史都是一化性的。各翅型的繁殖效益和限制因素。东方人比较
Control of seasonal wing dimorphism in the oriental mole cricket Gryllotalpa orientalis Brumeister (1839) from a wetland habitat in western Japan is described. The long-winged (LW) morph appeared from mid-June to September, whereas the short-winged (SW) morph appeared from September to mid-June. Individuals overwintered in either the adult or juvenile stage. The seasonal shift in wing morphology was linked to the overwintering stage. Individuals that hatched in May became SW adults in September-October and then overwintered, whereas those that hatched in June and July overwintered as juveniles and became LW adults in June of the following year. The life cycle of both morphs was univoltine. Reproductive benefits and constraints of each wing morph of G. orientalis are compared.
