Agrionympha karoo Agrionympha karoo Agrionympha karoo is a species of moth belonging to the Micropterigidae family. It was described by George W. Gibbs and Niels P. Kristensen in 2011. It is found in South Africa, where it is known only from the "Eastern Cape". It lives amongst "Adiantum" species and other ferns on rocky banks of streams where seepage maintains very limited growth of thallose liverworts and mosses in an otherwise hot and arid environment. The length of the forewings is about 2.5 mm for males 2.6 mm for females. The species is named after the semi-arid region in which it occurs,
Karoo the winter. Grasses are uncommon, making most of the biome unsuitable for grazing. The low rainfall, in fact, discourages most forms of agriculture. An exception is the thriving ostrich-farming industry in the Little Karoo, which is heavily dependent on supplementary feeding with lucerne. The difference between the Succulent Karoo biome and the Nama Karoo biome is that the former receives the little rain that falls as cyclonic rainfall in winter, which has less erosive power than the infrequent but violent summer thunderstorms of the Nama Karoo. Frost is also less common in the Succulent Karoo biome than in the Nama
