This very rare and local species has not been seen in LX for a very long time. Very likely extinct.
Native
Wingspan: 18–34 mm.
The fully grown caterpillar hibernates in a sturdy web on or in the ground. In the spring the caterpillar is still active for a short period and in April pupation takes place in a cocoon on or in the litter layer.
The species is both diurnal and nocturnal. The male comes to light, the female is sometimes active at the end of the afternoon in warm weather.
The flight period is mid-May towards mid-July in one generation a year.
The larva feeds on herbs like Filipendula ulmaria.
It inhabits marshes, wet meadows and hay fields.
