''Cyrtothyrea'' is a small genus of Afrotropical chafer beetles. They are about 9 mm in size, black in colour with white dots or lines on the thorax, elytra and abdomen. Each species has its own distinctive pattern. ''Cyrtothyrea'' are active during the day, and are often found on flowers, while feeding on nectar. They are pollinators of several plant groups, including lily, orchid, protea and asclepiad species. In the case of ''Lilium formosanum'', ''C. marginalis'' beetles feed on the anthers or force themselves deep down into the perianth tubes to feed on nectar. At times they contact the stigma, which may also be used as a launch pad for taking off.〔 ==Species== * ''Cyrtothyrea marginalis'' (Swartz, 1817) * ''Cyrtothyrea rubriceps'' (Raffray, 1877) * ''Cyrtothyrea rudebecki'' Schein, 1960 * ''Cyrtothyrea testaceoguttata'' (Blanchard, 1850) File:Cyrtothyrea marginalis, Krantzkloof Natuurreservaat, b.jpg| 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cyrtothyrea」の詳細全文を読む スポンサード リンク
