Pseudeustrotia candidula ([Denis & Schiffermüller], 1775)

Host plants:
The larvae feed on Polygonaceae, especially Rumex species like R. obtusifolius or R. crispus, but also Polygonum.

Habitat:
Pseudeustrotia candidula usually inhabits extensively managed, but not too nutrient-poor humid meadows, also along ditches, woodland edges or disturbed places.

Life cycle:
The pupa hibernates. The moths occur in one or two overlapping generations between May and August/September. The larvae are found between June and September or October. They can be beaten out of large Rumex plants though they usually live more near the ground.

Remarks:
Pseudeustrotia candidula occurs from northern Spain (Pyrenees) and parts of western Europe (locally in Great Britain) across central, east and southeast Europe and temperate Asia to Japan. The larvae can be distinguished from Deltote sp. - which feed on grasses - by the well developed prolegs.
