In total, 76 moth and 12 butterfly species from 14 superfamilies and three families, respectively, have been identified in and around Katima Mulilo, a town in northeastern Namibia. The most speciose families were Noctuidae (22 spp.) and Geometridae (9 spp.). Forty-three species were recorded for the first time in Namibia, including 19 from the family Noctuidae and 7 from the family Geometridae. The present study suggests that the moth fauna of Namibia, especially of the families Noctuidae and Geometridae, is largely unrecorded in the Zambezi Region, and perhaps elsewhere in Namibia.
