在花展裡遇到牠的，拍牠時只是認為又一隻食蚜蠅入鏡。
回家整理照片時，翻遍網路上的圖鑑竟然沒有牠的身影，以當時親眼所見牠的飛行方式，可以肯定的說是食蚜蠅沒錯，特有的飛行中定點停住是錯不了的。 但既然食蚜蠅三字找不出任何有用的資訊，那麼就以蚜蠅兩字做為關鍵字搜尋，逐條細看每個可能的名稱後，粗股兩個字感覺挺有關連的，便點了進去，嘩~真的就是牠~ 拍照時並沒有看清楚腳的模樣，是檢視照片時才注意到那雙後腿真的是非常的特殊，胖胖的粗粗腿，圖鑑上沒有一隻具備這樣的粗腿哩 看了一些有牠的連結，都不是在台灣 要再努力找資料囉
特別感謝 香港的 eastman 大大熱心說明 也才得以順利認識這位少見的嬌客 還要感謝空心竹 若不是提出可能是木蚜蠅的說法 我這不靈光的腦袋是不會想到縮減關鍵字去搜尋的 這邊有較詳盡的資料說明-轉貼如下 Size ：body length 6.5 - 9.5 mm Range ：all of United States and southern Canada (absent from the arctic) also occurs in Mexico, Eurasia, and the Orient Habitat ：adults are found in fields and grasslands with flowers larvae live in wet decaying organic matter such as manure, compost, and silage Season ：adults fly from late April to October in the north (Ontario); probably earlier and later in the south Food ：adults take nectar from flowers of a wide variety of herbaceous plants larvae feed on wet decaying organic matter such as cattle dung and silage See Also ：In North America, Syritta flaviventris occurs only in Texas and Mexico; it has a prominent projection near the base of the hind femur - lacking in S. pipiens
