A very rare and local species in Belgium, most records are from the southern provinces and from the Kempen.
Wingspan: 19–27 mm.
Can be easily confused with Chlorissa cloraria but the ground colour is lighter green, the costa is concolorous with the ground colour or more whitish and the postdiscal white line on the hind wings is more straight.
The adults are active from dusk on and come to light occasionally.
The adults fly from late May till July.
The larva is polyphagous on many species of lower plants and trees, it has been recorded a.o. on: Calluna vulgaris, Betula or Salix.
Thermophilous, heathland, sparse grassland on low nutrient, sandy soils.
