I noticed that this cricket species has been active throughout the fall and early winter. It's the first time I've observed crickets singing during this season in Japan. I have the impression that this winter is quite mild.

このコオロギの種類は秋から初冬にかけて活動しているのを見ました。日本でこの季節にコオロギが鳴くのは初めてです。この冬はかなり穏やかな印象があります。
