Collops beetle
Collops cribrosus is a soft-winged flower beetle in the Melyridae, first described by LeConte in 1852. The belongs to the Collops, which comprises predatory beetles frequently associated with flowering plants where they hunt small prey. Like other members of its genus, C. cribrosus is recognized as a beneficial insect in agricultural contexts, serving as a natural enemy of pest insects. The species has been documented in western North America, with confirmed records from British Columbia.

Identification
Collops cribrosus can be distinguished from other Collops by the specific arrangement and of punctures on the (the species epithet "cribrosus" refers to this sieve-like punctation pattern). Members of the Collops are generally characterized by soft, flexible elytra, a somewhat flattened body form, and often striking coloration with red or orange and black markings. Accurate species-level identification typically requires examination of genitalic structures and detailed punctation patterns, best confirmed by comparison with or expert determination.
