共生の森でモンキアゲハを見つけました。９０～１１０mmほどの大型のチョウです。関東以南で見られますが、近年分布を北へ広げているようです。この写真ではほとんど隠れてしまっていますが、和名は後翅にある黄白斑に由来します。


I found this butterfly called "Monkiageha(モンキアゲハ)" in the Kyoseinomori-Forest(共生の森). They are a kind of large butterfly that are from 90mm to 110mm long. They live in the Kanto Region or other places to the south of Kanto. However, these years they are expanding their habitat to the north. The name comes from the yellowish white patterns on their hind wings, although the patterns hide under the fore wings in this photo.
