A rather rare species in many areas of Belgium, less observed in the south.
Can be separated from Agonopteryx heracliana by its greater size and by the presence of 5 faint grey lines in the hindwing cilia.
Green, with dorsal and dorsolateral lines darker green; head capsule dark brown to black; prothoracic plate greenish brown, black laterally; last abdominal segment green with some blackish dots; pinacula black.
The caterpillar sometimes feeds on the flowers or seed of the foodplant, but lives more commonly on the leaves from a tube which it constructs by spinning a leaflet downwards; several such tubes are constructed during the entire development. June–September.
Pupation on the upper layers of the soil or amongst leaf litter; July–September.
The species hibernates in the adult stage. The adults are active at night and sometimes come to light; after hibernation they easily come to sugar.
One generation a year: from July and after hiberantion till May.
Oligophagous on many species of Apiaceae, like: Angelica sylvestris, Daucus carota, Heracleum sphondylium, Selinum carvifolia, Silaum silaus, Chaerophyllum, Pastinaca sativa, Anthriscus, Peucedanum palustre or Meum.
Very different kinds of habitat as long as one of the larval foodplants is growing there.
