Similar Species
A certain similarity to Primrose Erdeule ( Diarsia mendica ), but in which predominate yellow-brown or bright red-brown hues. The plantain Erdeule ( Diarsia rubi ), the bog meadows Erdeule ( Diarsia dahlii ) and Diarsia florida and Diarsia guadarramensis are all drawn less contrast, they lack violet tints and the moths are smaller.
Geographical distribution and habitat
The species is found throughout most of Europe. Eastwards ranges the spread to central and southern China, and Japan. East Asian individuals belong to ssp. urupina. The Primrose Erdeule inhabited preferably deciduous mixed and coniferous forests, heaths, raised bogs and parklands.

Visit artificial light sources as well as bait, and occasionally the flowers of the ordinary black cherry ( Prunus padus ), the flutter - rush ( Juncus effusus ) or of dwarf elder (Sambucus ebulus ). The caterpillars are found from September. They feed on a wide variety of plants, for example by:
- Männerfarn ( Dryopteris filix- mas ).
- Forest - Wood-rush ( Luzula sylvatica),
- Wire Schmiele ( Deschampsia flexuosa ),
- Forest Zwenke ( Brachypodium sylvaticum ),
