Small dusty wave Wikipedia
The small dusty wave (Idaea seriata) is a moth of the family Geometridae. It is found throughout Europe, the Near East, and North Africa. In the British Isles it is common in England and Wales but is only found in the eastern half of Scotland and is absent from Ireland.
The species is very small (wingspan 19–21 mm) and is probably one of the least striking members of the whole family, being basically grey with all markings indistinct apart from the black discal spot typical of the genus. Either one or two broods are produced each year and the species can be seen on the wing any time from June to September , flying at night and sometimes coming to light.
The larva feeds on ivy and the species overwinters in this form.
