http://dbpedia.org/resource/Andricus_quercuscalicis an entity of type: Eukaryote
Andricus quercuscalicis est une espèce d'insectes hyménoptères de la famille des Cynipidae. Ce petit insecte provoque par ses piqûres la formation de galles lamellées, dures, munies de crêtes longitudinales, sur les glands et cupules notamment du chêne pédonculé. Les femelles agames (ou parthénogénétiques) sortent des galles de février à avril.

Andricus quercuscalicis is a gall wasp species inducing knopper galls. Knopper galls develop as a chemically induced distortion of growing acorns on pedunculate oak (Quercus robur L.) trees, caused by gall wasps, which lay eggs in buds with their ovipositor. The gall thus produced can greatly reduce the fecundity of the oak host, making this gall potentially more of a threat to the reproductive ability of the tree than those that develop on leaves, buds, stems, etc. The Turkey oak (Quercus cerris L.), introduced into Britain in 1735, is required for the completion of the life cycle of the gall. The knopper is a recent introduction to the British Isles, first arriving in the 1960s and now found throughout England, Wales and as far north as Scotland; first occurring for example in 2007 at Eg
