What prevents the female Winter Moth from actively seeking mates during the flight window?
Answer
Females are almost entirely wingless, possessing only very small, functionless wing remnants.
The disparity in appearance and mobility between the sexes is a defining characteristic of the adult Winter Moth. While the male is capable of flight, the female is fundamentally flightless. This is because she possesses either no wings or only remnants that are too small and non-functional to allow her to fly. Consequently, the entire burden of locating a mate falls upon the male moth, who must fly to find the stationary female, who remains attached to the location where she emerged, usually on tree trunks or low vegetation, during the brief period when the weather permits flight.
