Horisme radicaria (De La Harpe, [1855])

Host plants:
The larvae feed on Clematis species, perhaps also on other Ranunculaceae.

Habitat:
Horisme radicaria inhabits usually quite low altitudes and warm habitats. It uses a broad variety of habitat types from riparian woodlands to xerophilous slopes.

Life cycle:
The adults usually occur in two, rarely also three generations between late April and September. The larvae are found well into October or even November. The usually blackish brown pupa hibernates.

Remarks:
Horisme radicaria occurs in some regions of southern and central Europe.
