Cometaster is a monotypic moth genus of the family Erebidae erected by George Hampson in 1913.[1] Its only species, Cometaster pyrula, the faint owl moth or ying-yang moth, was first described by Carl Heinrich Hopffer in 1857.[2] [3]
It is found in Eastern and Southern Africa, mainly in Botswana, the Democratic Republic of the Congo, Malawi, Mozambique, South Africa, Zambia and Zimbabwe.
In October 2004, as part of a biological control project, larvae of this moth from South Africa were released in Queensland, Australia, in order to keep under control the type of acacia Acacia nilotica subsp. indica, a major invasive species in the Mitchell Grass Downs.[4]
