Idaea ochrata

Idaea ochrata, known as the bright wave, is a moth of the family Geometridae, the geometer moths. It is found in Europe. The adult has a wingspan of 21 to 24 millimetres and flies at night, in one generation a year, from late June to early August in the British Isles; the flight season may vary elsewhere in its range. The species overwinters as a larva. In captivity the larvae have been fed on the flowers of hawk's beard, dandelion and coltsfoot, while in the wild they are recorded feeding on smooth tare and the flowers of hare's-foot clover.
