东方蟋蟀Gryllotalpa orientalis在翅型上表现出变异。在冲绳种群中，没有观察到短翅个体，也没有发现翅型二型。飞行行为G.在冲绳，从4月到10月观察到东方。相比之下，兵库种群表现出季节性的翅膀二型性，长翅个体出现在6月至9月。长翅变种的飞行期与这一时期相吻合。短翅的个体从9月到次年6月出现，它们从不飞行。两个种群均表现出一化性生活史。考虑到这两个地区的蟋蟀可能的飞行时期，翅膀图案和生活周期，推测当成年人不能体验适合飞行活动的温度时，预计会出现不飞。
The oriental mole cricketGryllotalpa orientalisexhibits variation in wing dimorphism. In an Okinawa population, no short‐winged individuals were observed, and wing dimorphism has not been detected. Flight behavior ofG. orientaliswas observed from April to October in Okinawa. In contrast, a Hyogo population exhibited seasonal wing dimorphism and long‐winged individuals appear from June to September. The flight period of the long‐winged morph coincided with this period. Short‐winged individuals appeared from September to the following June and they never fly. Both populations showed univoltine life cycles. Considering the possible flight period, wing pattern and life cycle of mole crickets in these two areas, it is presumed that flightlessness is expected to arise when adults can not experience suitable temperatures for flight activity.
