Eucnemidae, or false click beetles, are a family of elateroid beetles based on the type genus Eucnemis; they include about 1700 species, distributed worldwide.
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.
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).
Click beetle larvae, called wireworms, are usually saprophagous, living on dead organisms, but some species are serious agricultural pests, and others are active predators of other insect larvae. Some elaterid species are bioluminescent in both larval and adult form, such as those of the genus Pyrophorus .

Melasis buprestoides is a species of false click beetles native to Europe. [2] [3] The species name buprestoides (from the beetle genus Buprestis, and Ancient Greek ειδής eidēs, "like") refers to the species' body shape. [4] Linnaeus's original name for the beetle was Elater buprestoides.

Elateriformia is an infraorder of polyphagan beetles. The two largest families in this group are buprestids, of which there are around 15,000 described species, and click beetles, of which there are around 10,000 described species. The infraorder consists of six superfamilies: [1] Buprestoidea — the metallic wood-boring beetles
