Host plants:
The larvae feed on Fabaceae, usually brooms (e.g. Calycotome sp. near Teruel).
Habitat:
I observed Heterogynis canalensis in a mosaic of nutrient-poor grassland, scrub and oak woodland in the western Spanish Pyrenees. The most important habitat type should be bushy grasslands. Near Albarracin (Teruel) Heterogynis canalensis inhabits gappy broom (Calycotome) in sheep pastures.
Life cycle:
The life cycle should be similar to Heterogynis penella. I observed cocoons and adults in early July 2010 in the west Pyrenees and larvae in May 2018 near Teruel.
Remarks:
Heterogynis canalensis occurs in Spain, e.g. in Central Spain near Teruel or in the Spanish Pyrenees and their southern extended foreland. In France, it is restricted to a few sites in the eastern Pyrenees.
