Alaus oculatus can reach a length of about 25–45 millimetres (1.0–1.8 in). [2] They have an elongated body, black in color throughout. The pronotum exhibits a large oval patch of darker scales, framed in white, on each side - the common name of the beetle derives from this feature.
Elateridae or click beetles (or "typical click beetles" to distinguish them from the related families Cerophytidae and Eucnemidae, which are also capable of clicking) are a family of beetles. Other names include elaters, snapping beetles, spring beetles or skipjacks. This family was defined by William Elford Leach (1790–1836) in 1815.

When a click beetle bends its body, the peg snaps into the cavity, causing the beetle's body to straighten so suddenly that it jumps into the air. [ 5 ] Most beetles capable of bioluminescence are in the Elateroidea, in the families Lampyridae (~2000 species), Phengodidae (~200 species), Rhagophthalmidae (100 species) and Elateridae (>100 species).
These beetles are among the brightest bioluminescent insects. [1] With a brightness of around 45 millilamberts, [2] they are said to be technically bright enough to read by. [3] They achieve their luminescence by means of two light organs at the posterior corners of the prothorax, and a broad area on the underside of the first abdominal segment.

Eucnemidae, or false click beetles, are a family of elateroid beetles based on the type genus Eucnemis; they include about 1700 species, distributed worldwide.
This species was discovered by the lighthouse keeper Andreas Sandager on North Brother Island in Cook Strait, and was described by Broun in 1881. [3] [6] It is currently only found on islands in the outer Marlborough Sounds in New Zealand; [6] fragments of this beetle have been collected from the nest of the extinct Laughing owl in North Canterbury, indicating it once had a much larger former ...
