Western Blood-red Lady Beetle (Cycloneda polita)

Arthropoda > Insecta > Coleoptera > Polyphaga > Cucujoidea > Coccinellidae

A medium-sized (4-6mm) lady beetle with immaculate red elytra found throughout western North America where they are common predators of aphids. Several other spotless red lady beetles occur in California, most notably Cycloneda sanguinea, but pronotum markings are distinct. Cycloneda munda is nearly nearly identical but allopatric, occurring only on the east coast; a single California record from the SBMNH collection seems questionable.
