Alaus oculatus can reach a length of about 25–45 millimetres (1.0–1.8 in). Body is long and thin. Elytrae are black and have a mottled pattern marked with patches of silvery whitish scales. These large beetles show on the pronotum characteristic huge oval black eyespots with a white ring around each. The "false eyes" presumably afford a protection from predators by frightening them.
Eggs are laid in soil. Larvae are predators of beetle larvae feeding in decaying wood, especially cerambycids. Adults can be found from April to September (one specimen found in Blueridge Parkway, mile 272, on 11 Sep. 2016) X
