蠅的饗宴 Fly Banquet

科學圖說 Scientific introduction

一般人對雙翅目昆蟲的印象，是蚊蠅之類的害蟲，其實這群種類繁多的昆蟲，有各式各樣的食性，及相對應五花八門的口器構造。大琉璃食蟲虻擅長在空中追捕昆蟲，以尖利的口喙將消化液注入獵物體內，吸食分解後的體液；艷細蠅以舐吮式口器取食腐酵的落果；柄眼蠅則在姑婆芋葉面上舔食鳥類的排泄物。

In general, humans treat Diptera (flies) as pests. However, this group exhibits diverse feeding habits and specialized mouthparts. Microstylum oberthiiri robber fly is adept at hunting prey. It uses its sharp proboscis to inject digestive saliva into its prey and then sucks up the fluid following the decomposition of its tissues. The black scavenger fly has specialized mouthparts for sucking the sap from fallen fruit. A stalk-eyed fly feeds on bird excrement on the leaf of a giant upright elephant ear plant.
