Green coffee scale Coccus viridis (Hemiptera: Coccidae), new to Britain.
The Neotropical green coffee scale, Coccus viridis (Green) (Hemiptera: Coccidae), is reported breeding on indoor plantings in Britain for the first time. It was detected in the Humid Tropic Biome at The Eden Project, Cornwall, England, in November 2010; its origin and pathway of introduction are unknown, although its widespread distribution and abundance within the Biome indicates that it may have been present for several years. It was frequently attended by the white-footed ant Technomyrmex albipes Smith (Hymenoptera: Formicidae), which is suspected to have spread the scale within the Biome. The biology, economic importance and geographical distribution of C. viridis are reviewed. New host plants reported for C. viridis are Alstonia scholoris (Apocynaceae), Garcinia mangostana (Clusiaceae), Jasminum sp. (Oleaceae), Manicaria sp. (Arecaceae), Mormolyca polyphylla (Orchidaceae) and Rothmannia annae (Rubiaceae).
