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.
Bioluminescent click beetles are found throughout tropical, subtropical and temperate America. Species from Texas, Florida, Puerto Rico, and Cuba are now in different genera in the tribe Pyrophorini, such as Deilelater and Ignelater. [2] Adult Pyrophorus beetles feed on pollen and sometimes small insects, such as aphids or scale insects. Their ...

Alaus oculatus (Linnaeus, 1758) - eyed click beetle; Alaus oklahomensis Hatch, 1930; Alaus pantherinus Candèze, 1881; Alaus patricius Candeze, 1857; Alaus plebejus Candèze, 1874; Alaus zunianus Casey, 1893
Beetles with somewhat flattened, highly mobile larvae include the ground beetles and rove beetles; their larvae are described as campodeiform. Some beetle larvae resemble hardened worms with dark head capsules and minute legs. These are elateriform larvae, and are found in the click beetle (Elateridae) and darkling beetle (Tenebrionidae ...
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.
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 ...
