Neumeyer: Fauna Helvetica 20: Apidae 5. Centre Suisse de Cartographie de la Faune, 2007〕 The blue carpenter bees fly from mid-March to mid-October,〔 collecting pollen at various families of plants, especially knapweed (''Centaurea''), yellow composites (Asteraceae) and ''Lotus'' (Fabaceae).〔(Essex Field Club )〕 Females nest in the vertical or slanted dead plant stems,〔〔 such as thistles, blackberries (''Rubus'' species),〔 elderberries (''Sambucus'' species) and roses.〔〔 Then they provide the cells with a mixture of regurgitated nectar and pollen to feed the larvae.〔 Adult males and females overwinter inside their cells into the stems. Often several insects spend the winter together.〔 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「Ceratina cyanea」の詳細全文を読む スポンサード リンク
