Host plants:
The larva feeds on Clematis vitalba. Apparently, the caterpillar is able in certainly very rare cases to develop also on other deciduous woods (Lonicera, according to literature).

Habitat:
Horisme tersata inhabits almost all Clematis locations as riparian forests, forest edges, hedge areas or quarries.

Life cycle:
The moths fly in cool areas usually only in a single generation from late May to July, but otherwise generally in two generations from late April to June and from late July to early September. The caterpillar lives from late May to early or mid-October. The pupa overwinters.

Remarks:
Horisme tersata occurs from central Spain across Southern and Central Europe and temperate Asia to Japan. In the north it is still present in Southern Scandinavia.
