Hydrophilus palpalis is a species of water scavenger beetles belonging to the Hydrophilidae family. Some authors have included this species in a distinct genus (''Diboloceus''), but most of them consider ''Diboloceus'' just a subgenus of ''Hydrophilus'' (''Hydrophilus (Dibolocelus) palpalis'').〔〔 ==Description and behavior== This large species has an oval and moderately convex body. The basic color of the body is dark brown or black. Antennae are 9-segmented. Prosternum is well developed, divided into two lobes. Elytra show ten extremely fine striae. Hind femora are glabrous.〔 Roberto Arce-Pérez y Miguel Ángel Morón (The genus Hydrophilus (Coleoptera: Hydrophilidae: Hydrophilina) in Mexico and Central America ) Instituto de Ecología, A.

The first-stage larvae and the adults are excellent swimmers. Adults are mainly vegetarian while the larvae are carnivorous and have a preference for molluscs.〔 Marcia Maria Dosciatti de Oliveira, Juan Antonio Regil Cueto, Cristiano Dalla-Rosa and Leonardo Henrique Matias (ASPECTOS DA BIOLOGIA DE Hydrophilus (Dibolocelus) palpalis Brullé, 1837 (COLEOPTERA : HYDROPHILIDAE) ) Universidade de Caxias do Sul - UCS 〕 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「Hydrophilus palpalis」の詳細全文を読む スポンサード リンク
