Hensericho, which is very common in Japan. Compared to other butterflies, it has a rather plain appearance. The whole body is yellowish brown. There are four silver stripes on the underside of the hind wings. Silver crests also line the forewings, but are not as large as those on the hindwings. It has big black eyes. It flies pretty quickly.
It occurs from early summer to the end of summer and can be seen until around October. Collects nectar from flowers, rotten fruit and wet ground. The larvae eat grasses such as rice and pampas grass.
Since the larvae feed on rice, it has been regarded as a pest. When a large outbreak occurs, it eats up rice plants.
I took a picture of it perched on a leaf in Katakura Castle Ruins Park, Hachioji City. It was a solid with a slightly brownish color. The yellow scales on the wings were falling off and the tips were missing.
Her eyes were big and she looked cute.
