Euproctis chrysorrhoea (Linnaeus, 1758)

Host plants:
The caterpillars are polyphagous on all sorts of deciduous trees, especially Pyrus, Prunus and Carpinus.

Habitat:
Euproctis chrysorrhoea inhabits hedgerows, alleys, shrubby grasslands, dunes, warm, bright forests, orchards and similar places.

Life cycle:
The small caterpillar overwinters sociable in webbed leaves on the woods and is mature in the end of May or in June. The moths fly from June to August.

Endangerment factors:
Euproctis chrysorrhoea is unthreatened, but also rarely a pest. If they occur commonly, then mostly in economically insignificant terrain such as highway side green. Euproctis chrysorrhoea lacks large areas, such as the greater part of the northern Alpine foothills and the Swabian Alb. The moth is found mainly in warm lowlands such as the upper Rhine valley.

Remarks:
In the orchard, Euproctis chrysorrhoea has mostly disappeared through intensive spraying. Euproctis chrysorrhoea tends to outbreaks, but these collapse usually without real damage after several years without spraying. The trees die only in very rare cases and a combination of several unfavorable factors.

Euproctis chrysorrhoea is distributed from North Africa across Europe (missing only in the Far North) to the Middle East (Iran).
