Fenton's wood white (Leptidea major morsei)

It lives in the light and rare woods of deciduous forests, preferably in the hilly-sub-mountainous area. Lathyrus-rich plant species are the main habitat. Lathyrus flowers are the main source of nectar. The eggs are laid in isolation on the leaves or stems of these plants, which then develop larvae. 

High density areas: in the vicinity of Viscri, Roadeş, Daia, Buneşti și Meșendorf.
