Lady Beetle (Nipus biplagiatus)

Arthropoda > Insecta > Coleoptera > Polyphaga > Cucujoidea > Coccinellidae

A small (1.5mm) elongate lady beetle, black with red or yellow coloration in the form of 2 large spots on the elytra and on the anterior margin of the pronotum. The species is endemic to California and is apparently a scale predator; I have found the species on sycamore trees infested by the Sycamore Scale in Long Beach (Los Angeles County) . It is most similar to N. occiduus, another southwestern species that Gordon claims doesn't occur in California, though one 2005 specimen of N. occiduus in the SBMNH collection from Riverside County contradicts this. One other species, Nipus niger, is known only from northern California (Sonoma County). Gordon presents a key to the species.
