In Japanese Islands, one kind of field cricket, Velarifictorus micado, is distributed from Hokkaido to Yakushima and Tanegashima in Kagoshima Prefecture, and the other one, V. grylloides is from west of Chiba Prefecture on Honshu to the Nansei Islands. Both species have a similar morphology and a univoltine life cycle in the area north than Kyushu. However, they differ in that V. micado overwinter as eggs, emerging as adults from early/mid-August to October, whereas V. grylloides have non-diapause eggs, instead overwintering as nymphs and emerging as adults in June and July. The species can be interbred in laboratory setting
