A very rare and local heathland species in Belgium, only known from the southern part of the country. In 2006 after a long period of absence, a single individual was trapped in AN, followed by a few other observations in 2014, 2015 and 2021.
This declining species is rarely seen.
The adults fly in one generation a year: from end of March till begin of June. They rest during the day on trunks of young Betula and small conifers. They are attracted to light in low numbers.
The larva lives on various species of low plants and decidious trees including Betula and Myrica gale. Hibernates as a young larva on the food plant and pupates later amongst detritus.
