The African Stoermeriana are closely related to the Streblote genus and many species have been moved from Streblote to Stoermeriana and vice versa. The Afromoths database lists 49 species, but I'm not sure this is the exact number. Many species look very much alike and may in the end turn out to be the same. Probably more species will be described the following years.
Most species are on the smaller side or at best medium sized. This is something only the diehards would rear. The moths are not particular attractive, even though the caterpillars often look quite nice. Specially because they group together in very large colonies. If you obtain eggs do not hesitate to rear them, the early stages of many species are still unknown and they are not particularly difficult.
