What is the surprisingly narrow, late-autumn flight window for the adult Winter Moth in the northern hemisphere?
Answer
Late November and December
Although the moth's name suggests a deep winter insect, the critical observation window for the adult moth is surprisingly narrow, occurring in the late autumn. This period, typically concentrated in late November and December in the northern hemisphere, is crucial because it is when many other moth species have ceased activity. This late-season flight is biologically essential as it provides the necessary timeframe for the wingless females to lay their eggs before the ground freezes completely, thus ensuring the next generation's survival cycle.
