A very rare and local species in LI, only known from very old records. More than likely extinct.
Hibernates as a young larva on the food plant and pupates later in a cocoon among plant debris.
The adults are active from dusk on and later come to light.
The adults fly from half July till late August, in one generation a year.
The larva lives on Calluna vulgaris, Cytisus, Rumex or Lotus.
