Description
Opheroptera brumata male. It is one the few Lepidopterans to be active on early Winter, the male is fully winged, while the female is flightless with vestigial wings. While this moth can be a pest, it still shows a wonderful evolutionary adaptation by being active during this late, because it can avoid many of its potential predators, birds and larger insects, spiders. It is also capable of endothermy to keep itself warm during the cold weather.
