Host plants:
The larvae feed on Oxycoccus palustris.
Habitat:
Carsia sororiata usually inhabits bogs with large stands of Oxycoccus.
Life cycle:
The moths occur between June and August (especially in July). The egg hibernates. The larvae live between mid-April and early July near the ground on the host plant. I found them especially in June.
Endangerment factors:
In central Europe Carsia sororiata is heavily endangered due to the destroyment of most bogs. The few remaining bogs must be stabilized hydrologically and preserved from all other influences.
Remarks:
Carsia sororiata has a huge range, but is often only very local: N-America, central and northern Europe, N-Asia.
