The Notocrypta Curvifascia is commonly known as the Restricted Demon Butterfly and belongs to the Hesperiidae Family. It was first published in 1862.
The Restricted Demon is approximately 4 cm long when fully grown. Its wings are dark brown to black, with a white spot near the trailing end.
When I first saw this butterfly I thought that it was a moth due to the greyish brown appearance.
