Alaus oculatus, preserved specimen


Alaus oculatus can reach a length of about 25–45 millimetres (1.0–1.8 in).[1] Body is long and thin. Elytrae are black and have a mottled pattern marked with patches of silvery whitish scales.[1][2] These large beetles show on the pronotum characteristic huge oval black eyespots with a white ring around each.[3] The "false eyes" presumably afford a protection from predators by frightening them.[4]

Life Cycle[edit]

Eggs are laid in soil. Larvae are predators of beetle larvae feeding in decaying wood, especially cerambycids.[1] Adults can be found from April to September (one specimen found in Blueridge Parkway, mile 272, on 11 Sep. 2016)[3] X


Their diet consists of nectar and plant juice. The larva's diet consists of grubs and wood-boring beetles.[3]

Distribution and habitat[edit]

This species is present in Central and North America.[1][3] It can be found in deciduous/mixed forests and woodlands.[3]
