不是蜂鳥是天蛾 this is hummingbird hawkmoth, not the bird

蜂鳥只能在南美找到。這天在濕地公園遇到她在這邊世界的化身。她叫小豆長喙天蛾。第一次遇到這神奇昆蟲!

it is said that hummingbirds only exist in south america. mother nature, i guess, therefore chooses hummingbird hawkmoth to grace the norther hemisphere. according to wiki, the hummingbird hawk-moth is distributed throughout the northern old world from portugal to japan, but is resident only in warmer climates.

原來這傢伙在北半球都有分佈,但不耐寒喜暖。擁有一條長長的「象鼻」,用來吸食花蜜。還有複眼。據說她們的視力是科學家研究的物件。

一個網上科學文章又說,長喙天蛾對人類肉眼是棕灰色,但在紫外線下,她們身上有黃、紫、綠的螢光。

same as hummingbird, this sphingidae species fed on nectar. thus the long proboscis.

an interesting fact pointed out by a.r. pittaway online on sphingidae of the western palaearctic :  to human eyes the forewings of most species are various shades of dull brown or grey; however, under ultraviolet light they yield characteristic fluorescent yellow, violet, purple and green patterns. to birds and other insects these seemingly dull species are probably brightly patterned.

翻究資料,讓我還認識到「趨同演化 (convergency)」。在演化生物學中,趨同演化是指兩種親緣關係很遠的動物,長期生活在相同或相似的生態系統,發展出外形及功能相似的器官,此種器官即為同功器官。

in digging information about this moth and hummingbird, i also pick up a biology term “convergent evolution”: in evolutionary biology, it is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
