濕地公園行 – 蜻蜓 wetland park dragonflies file

2012.5.26 雨 rain

初夏大雨時節,到濕地公園,收穫豐富。這是快速記錄蜻蜓/豆娘篇。資料多來自公園的網頁。heavy rain in early summer season turns out to be a rewarding trip at the wetland park. here is a quick record of dragonflies/damselflies I encounter. All the information is based on that from the park’s website.

黃蜻:黃蜻是濕地公園常見的蜻蜓。牠們的飛行能力甚強。在仲夏尤其是下雨前,常常可見到大群黃蜻在天空中飛舞。

wandering glider (pantala flavescens) is a common dragonfly in wetland park. its supreme flying skill has earned it the name ‘glider’. it is commonly seen in large groups during summer, especially before rain. even in winter, it is occasionally found in sheltered areas.

 

短腹異蜻:香港首次記錄

錐腹蜻:身型獨特,細小成錐狀,腹後半部明顯收窄。雄性成蟲為藍黑色,而雌性成蟲則主要為淡綠和黑色。錐腹蜻飛行能力不強,成蟲多數只會在雜草叢生的池塘或沼澤附近出沒。由發育、求偶至產卵,錐腹蜻整個生命週期都在該處完成。

asian pintail (acisoma panorpoides panorpoides) – the body shape of asian pintail is very unique and differs from other dragonfly species. its body is small and spindle-like, with the abdomen which is significantly narrowed at the last few segments. the adult male is blue and black while the adult female is mainly pale green and black. because of their weak flying ability, the adults of asian pintail are usually confined to swamps or weedy ponds. from growth, mating to ovipositioning, the species completes its life cycle there.

藍額疏脈蜻:藍額疏脈蜻的身軀主要由藍、黃、黑三種顏色組成,並有一對綠色的大眼睛,顏色對比鮮明。藍額疏脈蜻通常活躍於池塘和沼澤的草叢,偶然亦會在沿岸地區出沒。

blue dasher (brachydiplax chalybea flavovittata) is an attractive dragonfly with blue, yellow and black coloured body and a pair of green eyes. it occurs in weedy areas around ponds and marshes, and sometimes in coastal areas.

斑麗翅蜻:斑麗翅蜻的前翅和後翅布滿鮮艷的黑黃色圖案,飛行時就像蝴蝶般翩翩起舞。每當夏末秋初,斑麗翅蜻會聯群結隊地在天空飛舞。

variegated flutterer (rhyothemis variegata arria) is distinctive. its forewings and hindwings have a distinct pattern of black and yellow and it flies like a butterfly. variegated flutterers can be found gliding in a large group near the end of summer.

琉球橘黃蟌:琉球橘黃蟌體型較大和強壯,以體型較小的豆娘為獵物。與其他豆娘比較,強悍的琉球橘黃蟌的活動期較長,從春天至初冬都可發現牠們的蹤影。牠們橄欖綠色的合胸和橙紅色的腹部,令牠們在水生植物叢中非常顯眼。

orange-tailed sprite (ceriagrion auranticum ryukyuanum) is a large damselfly with strongly built body, and preys on smaller damselflies. this robust species has a long flight period from spring to early winter. with distinctive olive green thorax and orange red abdomen, orange-tailed sprite can be spotted easily even when it hides among aquatic plants.

另外,未能拍攝到但印象深刻的是玉帶蜻,因為他飛行盤旋但不願停留,惟黑身上一帶白色往往影入眼簾。there’s one dragonfly i cannot captured in photo but remember vividly. but its white patch on the waistline contrasts with the black body. it is called pied skimmer (pseudothemis zonata)
