''Sminthurus viridis'' is a member of the Collembola, the springtails, an order in the subphylum Hexapoda. The species is known by common names such as clover springtail, lucerne flea,〔(【引用サイトリンク】title=ITIS standard report - Sminthurus viridis (Linnaeus, 1758) )〕 or Lucerne earth flea. Common names such as Lucerne flea are misleading because, being a member of the Collembola, this species is not even remotely related to the fleas. Calling it a "flea" simply is a reference to its jumping ability and its small size.〔 〕 The species originated in Eurasia, but in particular in Europe. However, it has been spread unintentionally by human agency. It now is present in southern regions of Australia and Tasmania, where it is considered a pest.〔(【引用サイトリンク】 title= PestWeb - Lucerne Flea )〕 〔 (【引用サイトリンク】 title= Collembola - springtails )〕 It also is present in South Africa, New Zealand and the Americas. It is nowhere welcome, but its pest status varies from negligible to severe, depending on local circumstances.〔 ==Description== Like other members of the family Sminthuridae, ''Sminthurus viridis'' has a roughly globular body. The species varies in colour, but commonly is patchy bright green or yellowish.〔 As Collembola go, it is a fairly large species, commonly up to about 3 mm in length. The species has a well-developed furcula and it leaps actively if alarmed.〔Roberts, John & Umina, Paul. Lucerne Flea. AG0415. June, 2008 Centre for Environmental Stress and Adaptation Research (CESAR), University of Melbourne. Department of Environment, Land, Water and Planning (DELWP), Victoria, Australia〕 The mouthparts of ''Sminthurus viridis'' are mandibulate meaning that they have biting mouthparts, though only the tips of the mandibles project out of the mouth folds. 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「Sminthurus viridis」の詳細全文を読む スポンサード リンク
