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 (crater) of its craters exceeds the critical crater diameter. This would explain the crowding of giant craters, since none of these would result in global degradation. Indeed, if Karoo, at 33 km diameter, represents D and resurfaced the asteroid, then the 5 or more other giant impacts must have happened subsequently, which is highly unusual given that they are in fact almost just as large. Thus α = 1.33 from Fig. 2a is likely a lower limit on Mathilde’s attenuation. Karoo (crater) Karoo is an impact crater on the Asteroid 253 Mathilde, named for the Great Karoo Basin, a coal basin
