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
,也沒找到有詳細說明的部份,所以對於牠的了解目前還是不了的多
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

- 2樓. 陳明裕(阿川)2009/12/18 10:47股指的是大腿這一截吧
如果是 應該還是要稱為 粗股 比較好啦
我在扯啥......我是來問安的啦

平溪碌碌和啼燕。花蝶翩翩點翠顏。霧嵐嬉鬧漫巒攀。水竹間。還我幾多閑。 - 1樓. 空心竹2009/12/18 00:47沒看過的食蚜蠅
沒錯了~
我查過外國網頁
這隻確實是Syritta orientalis
