The meadow argus (''Junonia villida'') is a butterfly in the family Nymphalidae, commonly found in Australia. It is also known as Albin's Hampstead eye in the United Kingdom, where it has occurred only as an accidental import. ==Description== The meadow argus has two brownish wings, each covered with two distinctive black and blue eyespots as well as white and orange marks that appear on the edge of the wings. The eyespots are a defense mechanism that are not only used to frighten predators away, but also to confuse the predators into thinking that the eyespots are the target, allowing the butterfly to escape with only a small part of the wing being lost. The underside of the wings are mainly unmarked, except the lower part of the fore wing has similar markings as the upper side.〔 The wingspan measures 4 centimetres (1.6 in) in males and 4.3 centimetres (1.7) in females.〔(【引用サイトリンク】title= Meadow Argus (''Junonia villida'') )〕 As the butterfly rests, it can sit in four different positions depending on the current situation. These positions include: *If the sun is shining, the butterfly will open and relax its wings *If danger approaches while in the sunlight the butterfly will open its wings further revealing eyespots on its hindwings *If the sun is not shining the butterfly will close its wings *If danger approaches while there is no sunlight the butterfly will raise its frontwings revealing hidden eyespots 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「Meadow argus」の詳細全文を読む スポンサード リンク
