フィールド日記

 生徒たちに大きな蛾がいますと呼ばれて行ってみると、図書館の壁にモモスズメがとまっていました。交尾中で、上がメス、下がオスです。写真では前翅の下にあって見えませんが、後翅が桃色であることが和名の由来のようです。


As students said that they had seen big moths in the library, I went there and it turned out that "Momo-suzume (モモスズメ)" moths were on the wall of the library. They were mating and the upper one was a female while the lower was a male. "Momo (モモ)" in the name means "peach" and it comes from the fact that their hind wings are pink like peaches although we can't see them in the photo because they are under fore wings here.
