The variegated butterfly bat (''Glauconycteris variegata'') is a species of vesper bat. It is sometimes also called the leaf-winged bat, or simply the butterfly bat. It is not currently endangered, but may be threatened by habitat loss in some parts of its range.〔 ==Description== Variegated butterfly bats are relatively small bats, averaging in total length, with a tail, and weighing around . Females are slightly larger than males, with an average wingspan of , compared with a typical male wingspan of . The body is covered in long, silky fur of highly variable colour, although usually yellowish or light grey, and lacking the prominent patterns found on some closely related species. The fur on the undersides is white or very pale grey, and that on the face and ears is brown. The wing membranes also have a sparse covering of hair, and have a distinctive reticulated pattern of dark veins, from which the bat takes the first part of its name.〔 The bat has a domed head and a short snout with a deep groove running between the nostrils. The lower lip is large and padded, but the upper lip has a simpler appearance, without any of the folds seen in some other bat species. The ears are relatively short, with a small tragus.〔 The wings are long and narrow in shape, suggesting that the bat is agile in the air, but is not efficient at high speed flight. Its flight speed during foraging has been measured as . 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「Variegated butterfly bat」の詳細全文を読む スポンサード リンク
