The Rufous Minor (''Oligia versicolor'') is a species of moth belonging to the family Noctuidae. It is distributed throughout Europe from Bulgaria up to the Caucasus in the South. In the North southern Scotland, southern Sweden and Estonia through Europe to central Spain, southern Italy. The wingspan is 24–28 mm. This species is extremely similar to the Marbled Minor (''Oligia strigilis'') and the Tawny Marbled Minor (''Oligia latruncula'') and specific identification usually requires close study of the genitalia. See Townsend et al. 〔 Martin C. Townsend, Jon Clifton and Brian Goodey, 2010 ''British and Irish moths: an illustrated guide to selected difficult species'' (covering the use of genitalia characters and other features) Butterfly Conservation (pdf ) 〕 for genitalia images and an identification key.''O. versicolor'' has a wingspan of 23–28 mm and often has more brightly coloured forewings than its congeners with rich reddish-brown tones and a grey subterminal band. There is also often one or more tufts of reddish hairs on the thorax, always lacking in its congeners. Although melanism occurs in this species it is much less frequent than in the other two species. ''O. versicolor'' flies at night in June and July and is attracted to light and sugar.It prefers moist areas. These include, for example, meadows, moors, wet heath and fen, woodland areas, sometimes sandy soils, but not strongly xerothermic habitats. The larva feeds internally on the stems of various grasses (including ''Carex'' species, ''Luzula luzoloides'', ''Bracilypodium sylvaticum'' and ''Poa pratensis''), pupating in a cocoon among the roots. This species overwinters as a larva. # ''The flight season refers to the British Isles. This may vary in other parts of the range.'' ==References== *Skinner, Bernard ''Colour Identification Guide to Moths of the British Isles'' 1984 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「Rufous Minor」の詳細全文を読む スポンサード リンク
