Host plants:
In Fuerteventura, I found eggs particularly on stems, occasionally also leaf tops of Hirschfeldia incana and rarely Sisymbrium sp., usually at half height of 10-20cm above the ground. According to literature the species was observed on further Brassicaceae as Diplotaxis.

Habitat:
Euchloe belemia inhabits arid areas, ravines, rocky slopes, fallow land, roadsides and rural settlements.

Life cycle:
The adults fly in spring from late January to May, The caterpillars live mostly on flowers and fruits and develop very quickly. The pupae usually go into an aestivation as a development in the hot, dry summer months would be limited. They often emerge only after several years.

Endangerment factors:
In places, Euchloe belemia is threatened by overbuilding, tourism and overgrazing.

Remarks:
Euchloe belemia occurs in North Africa, some Canary Islands (Fuerteventura, Gran Canaria, Tenerife) and the south (rarely center) of the Iberian Peninsula in Spain and southern Portugal.
In recent years, the populations for example of the Canaries are separated as separate species. This is probably another case where a subspecies concept would be more helpful.
