Food

Remarks

introduced into California in 1892 for control of lecaniine scales (Coccidae). It was released at Santa Barbara and San Jose and is now established in coastal California. Unlike R. lophanthae, it apparently has not spread to other parts of the United States. (1)

Very similar to the darker-brown and black beetles in Tribe Scymnini, but all those beetles have pubescent eyes, hairs of only one length, and shorter antennae.

Rhyzobius lophanthae is reddish-brown with a distinctly paler pronotum.
