Apart from its greater size and slightly falcate forewings the species can be separated from the other Wood Whites in Europe (Leptidea spp.) by the conspicuous gliding flight displayed by the males. Fenton’s Wood White can be seen on damp, grassy vegetation at the sunny edges of woods, in grassy woodland clearings and on regenerating woodland on grassland. They occur almost exclusively in oak forest and mixed deciduous woods. This butterfly has two generations a year and hibernates in the pupal stage. The larvae feed on Peas, in Europe on Lathyrus niger or Lathyrus vernus with ova being laid almost exclusively on the plants in the shade. In Transylvania, an important larval food plant is the endemic Lathyrus hallersteinii. Habitats: broad-leaved deciduous forests (40%), mesophile grasslands (15%), humid grasslands and tall herb communities (10%), coniferous woodland (10%), mixed woodland (10%).

Fenton’s Wood White (Leptidea morsei) is a butterfly of the Pieridae family. It is found from central Europe to Siberia, Ussuri, Korea, northern China and Japan. The habitat consists of damp, grassy vegetation at the sunny edges of woods, in grassy woodland clearings and on regenerating woodland on grassland. They occur almost exclusively in oak forest and mixed deciduous woods.
The larvae feed on Peas, including Lathyrus niger, Lathyrus hallersteinii and Lathyrus vernus in Europe. Other recorded food plants include Vicia cracca, Vicia japonica and Vicia amoena. Hibernation takes place in the pupal stage.
