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 radicaria 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:
The photos on this page show Horisme radicaria. Until late April 2018 they have been wrongly listed here as H. tersata.
