Host plants:
Supposedly like its congeners on woody Rosaceae (Prunus, Crataegus, Pyrus).
Habitat:
Supposedly especially shrub-rich habitats in dry and warm environments.
Remarks:
Nychiodes notarioi has been described only recently from Spain. It is known there from the more northerly part of Eastern Spain (app. from Valencia, Cuenca and Teruel to the East Pyrenees) and should be endemic. But there is also the possibility that it will be found in the French East Pyrenees in future.
