✔ 最佳答案
A butterfly is an insect of the order Lepidoptera. The scope of the term butterflies depends on how far the concept is extended. Currently, most experts include the superfamilies Hedyloidea (the American moth-butterflies), Hesperioidea (the skippers) and Papilionoidea (the so-called 'true' butterflies). This concept of butterflies including the Hedyloidea is an only recently expanded one.[1] Like all Lepidoptera, butterflies are notable for their unusual life cycle with a larval caterpillar stage, an inactive pupal stage and a spectacular metamorphosis into a familiar and colourful winged adult form, and most species being day-flying, they regularly attract attention. The diverse patterns formed by their brightly coloured wings and their erratic-yet graceful-flight have made butterfly watching a popular hobby.

當butterflies採花蜜gr時候,身上黍上花粉
而butterflies再飛去第朵花採蜜,d花粉就會落到雄蕊ge柱頭
再一直落到子房,同卵子結合
果實就會慢慢成長,之後花朵會謝
果實就成熟啦~
