''Melanostoma mellinum'', is a very common species of hoverfly found in many parts of Britain, Europe, North Africa, Asia and North America. A small species, the wingspan range recorded is between 4.75 and 7 mm. Very similar to ''Platycheirus'' and other ''Melanostoma'' species but with close inspection of some finer details can be identified with certainty. Adult males closely resemble ''Platycheirus clypeatus'' but lack the flattening or broadening of the front legs characteristic of most ''Platycheirus'' males. Females resemble female ''Melanostoma scalare'' sharing similar triangular tergite markings but have a shiny, black frons which separates them from ''M. scalare'' and most ''Platycheirus'' species. Preferred habitat include grasslands and moorlands including those in hilly and mountainous regions. Adults can be found feeding on the pollen of grasses (''Poaceae'') and other wind-pollinated plants. Little is known of its biology, However the larvae are suspected to be general predator of small insects in leaf litter. Flight times in Britain and Ireland are from April to October with peaks in late May - early June and from July to August. ==References== 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「Melanostoma mellinum」の詳細全文を読む スポンサード リンク
