フィールド日記

高校校舎でヒカゲチョウを見つけました。どこからか迷い込んできたようです。雑木林周辺でよく見られる種で、不二聖心でもクヌギの樹液に集まっている様子が観察されています。幼虫の食草はササ類です。


I found a "Hikage-Chou (ヒカゲチョウ)" butterfly in the high school building. It seems to have strayed into the building. They are often seen around thickets. In Fuji-Seishin, they have been observed gathering to tree sap of the Japanese chestnut oaks. Their larvae eat Sasa plants.
