It is flattened and eyeless, resembling a flea or tick. It used to be placed in a separate family called Leptinidae, but is now placed in the family Leiodidae, in its own subfamily, Platypsyllinae.〔 ==Description== The beaver beetle has various modifications to suit its ectoparasitic mode of life. It resembles a flea or a louse in appearance and was originally placed in the flea family Platypsyllidae. It has no wings and no eyes, and its antennal clubs have the antennomeres numbered 3 to 11 shortened, compacted globularly, and partly enclosed in a scoop-shaped antennomere. The larvae are also ectoparasitic on beavers and have hooks on the three thoracic segments which enable it to cling to its host.〔 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「Beaver beetle」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
