The speckled wood (Aphantopus hyperantus) is a medium-sized butterfly in the family Nymphalidae. The upperside of its wings is dark, chestnut brown in color. The female has on the upperside of the forewings two pronounced black 'eye spots' with a light brown edge, and on the hindwings two or three such spots. The eye-spots on the upperside of the male's wings are barely visible. On the pale brown undersides of the wings there are characteristically arranged black 'eyes' with a dirty yellow edge and white center; on the forewings there are three, on the hindwings five.
The speckled wood flies along forest edges and through forest clearings, as well as shrubby and grassy areas, from the lowlands to the forest edge.
