Horisme tersata ([Denis & Schiffermüller], 1775)

Host plants:
The larvae feed on Clematis species and sometimes other Ranunculaceae like Pulsatilla or Thalictrum. Some records show that also Lonicera (Caprifoliaceae) can be used.

Habitat:
Horisme tersata inhabits a broad variety of habitat types from riparian woodlands to xerophilous slopes and subalpine, humid forests.

Life cycle:
The adults usually occur in two, sometimes even three generations between April and September. In high altitudes there should be only one generation. The larvae are found well into October. The usually redbrown pupa hibernates.

Remarks:
Horisme tersata occurs in many regions of Europe (not in the very north) and temperate Asia to Japan.

Hints on determination:
Horisme tersata is similar to H. radicaria and can be distinguished by the genitalia. Hints are possible by the black apical dish: it is not so distinct and the area above is not lighter in Horisme tersata, but in H. radicaria.
Pupa colour seems different.
