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,
Ryn Desert can drop to a low of . Many small towns are scattered throughout the Ryn Desert, and population density is between 1 and 15 people per square mile. The Ryn lies in a semi-arid climate zone, and receives very little rainfall. High winds sweep across the desert, and in 2001 a dust storm in the Baltic Sea was determined as originating in the Ryn Desert. A study of long-range dust transportation to the Baltic Sea region—by analyzing dust pollution in Scandinavia, showed that aerosol concentrations there were influenced more by the Ryn Desert region than the Sahara Desert in Africa.
