The Wolkberg zulu〔Woodhall, S. Field Guide to Butterflies of South Africa. Cape Town:Struik Publishers, 2005.〕 (''Alaena margaritacea'') is a species of zulu butterfly in the Lycaenidae family. It is endemic to South Africa, where it is only known from grassy slopes adjoining afromontane forest in the Haenertsburg area of the Limpopo Province near the Wolkberg. It is under severe threat from alien tree plantations as only two colonies are known to exist. The wingspan is 24–27 mm for males and 28–30 mm for females. Adults are on wing from late December to early January. There is one generation per year.〔Woodhall, S. Field Guide to Butterflies of South Africa, Cape Town: Struik Publishers, 2005.〕 The larvae feed on ''Cyanobacteria'' species. ==References== * Gimenez Dixon, M. 1996. (Alaena margaritacea ).
