Flight dimorphism has been considered to result from a balance of costs and benefits between flight capability and reproduction. The validity of the hypothesis, however, has been challenged recently. In this study, we examined the effect of flight time on trade-off between flight capability and reproductive development in Velarifictorus aspersus and we(More)
The effects of environmental factors and appendage injury on the wing variation in Velarifictorus ornatus (Shiraki) (Orthoptera: Gryllidae) were investigated. The percentage of micropters was more than 95% when the nymphs were reared at constant photoperiods, and changing photoperiod did not affect wing variation in V. ornatus at 25 or 30°C. In the crowding(More)
