Rhyzobius chrysomeloides, the round-keeled Rhyzobius, is a species of beetle in the family Coccinellidae. It is found in most of Europe, North Africa and northern Asia.[1]
Life History
R. chrysomeloides is a predatory species, feeding on aphids.[2] R. chrysomeloides can typically be found on various species of trees and garden shrubs, first being recorded in Britain in 1996 on a pine tree.
Description
Adults reach a length of about 2.55–3.15 mm (0.100–0.124 in). They have an elongate oval, elongate oval, distinctly flattened body. The pronotum is brown and the elytra are reddish with a black pattern. The antenna and legs are brown.[3] R. chrysomeloides is visually similar to Rhyzoius litura, but can be differentiated by its broader prosternal keel and the darker, U-shaped markings on its elytra.[2]
