Vedalia

 

(Rodolia cardinalis; also known as Novius cardinalis and Vedalia cardinalis), an entomophagous beetle of the family Coccinellidae (ladybugs) that destroys the cottony-cushion scale from Australia, which is a dangerous pest of citrus fruits. The body length is 3–5 mm. The beetle is red-black, and the larva is red. The vedalia is native to Australia. It was imported first to California and then to other citrus-raising regions, including the Black Sea shore of the Caucasus. The beetle has become acclimatized in these regions and has impeded reproduction of the injurious scale.
