During which period do male and female Winter Moths fly to mate?
Answer
Late fall or early winter, usually between late November and early January
The adult phase of the Winter Moth cycle is characterized by flight activity occurring much earlier than the damaging feeding stage. Both male and female adults are active during the late fall or early winter period, specifically cited as usually occurring between late November and early January. The primary purpose of this adult activity is reproduction: males fly to locate mates, and females lay eggs. This timing is distinct from the larval feeding period, which occurs much later in the spring when the new foliage emerges.
