Scopula immorata

Scopula immorata, known in English as the Lewes wave, is a moth of the family Geometridae, the geometer moths. It is found throughout Europe and the Near East. The wingspan is 20 to 27 millimetres, and in western Europe the moth flies in two generations, from the end of June to mid August. The larva feeds on various low-growing plants such as thyme and oregano. Mating begins with the males seeking out females in a simple courtship behaviour that takes place in the morning, at roughly six to ten o'clock, and lasts for an hour to an hour and a half. Two subspecies are recognised, the nominate Scopula immorata immorata and Scopula immorata duercki, described by Sheljuzhko in 1955.
