Abstract     Fenton's Wood White (Leptidea morsei (FENTON, 1882)) is one of the most threatened and understudied butterflies in Europe. It is in decline throughout its European range, but its distribution and the reasons for its falling numbers are unknown. Problems with identification have prevented more intensive scientific studies in the past. In order to help identify L. morsei in the field we provide detailed wing pattern analysis along with pre-imaginal descriptions and compare these with the similar L. sinapis complex. Characteristic adult behaviour and habitat preferences are also described. Ovipositing was observed exclusively on plants of Lathyrus niger (L) BERNH. along shady woodland rides and within the confines of light oak woodland. This specific habitat, possibly the most important factor concerning the limited distribution of L. morsei, is under threat due to the abandonment of coppicing, the impact of deforestation and habitat fragmentation. During recent surveys in Slovenia new colonies were discovered in the central part of the country but it was also noted that numbers were declining in previously stable populations. In order to reverse this rapid decline more studies regarding its distribution and ecological requirements are necessary to implement proper habitat management.
