“Unfamiliar butterfly”

A butterfly that I often saw from spring, were perched on the leaves of the doku-dami (chameleon plant). Several others were on the ground. They were “Ishigake-cho.” Ishigake means Japanese stone wall. The pattern of wings is likened to that shape. This butterfly is not known to be this peninsula. They probably entered the peninsula from south.  [JUNE 2021]

Cyrestis thyodamas

ある雑木林で出会ったイシガケチョウ。半島では存在があまり知られていません。紀伊半島以南に分布していますが、北上していると考えられています。翅の模様が、石垣に見立てられてその名前があります。
