Host plants:
The caterpillar lives on Populus species, more rarely also Salix.
Habitat:
Pheosia tremula colonizes grove-rich habitats, that usually have to be a bit air moist (riparian forests, swamp forests, forest edges, poplar avenues etc.).
Life cycle:
Pheosia tremula occurs in two generations (2nd often incomplete) from April to August. The caterpillars can be found from the end of May/June to October. They rest in the case of poplars often on the long petioles.
Endangerment factors:
Pheosia tremula is still at little risk, even if the moth is gradually declining (destruction of unprofitable softwoods, dark forest management).
Remarks:
Pheosia tremula is widespread in much of Europe and temperate Asia.
