The balcony observer's 184th report- Green lacewing 蚜獅變草蛉 (Chrysopa sp.)

草蛉是完全變態昆蟲,生活史包括卵、幼蟲、蛹、成蟲。

草蛉的卵,會以細絲立在葉子上,像是一顆氣球。蟲孵化離開後的空殼子,頂端有開口,像花開。

草蛉的幼蟲為捕食性,食量大,專門獵食小型昆蟲,有如一隻尖牙利齒的猛獸,又常見以蚜蟲等小昆蟲為食,因此俗稱蚜獅,是益蟲。蚜獅有一個特殊的習性,牠們會將行走時碰到的小碎物黏附在自己的背上,用以偽裝自己。這些小碎物通常為植物碎片、吸食過的獵物屍體。因此像個拾荒人,整天把全身家當都背在背上走來走去。

蚜獅蛻變後的成蟲,是全身綠色,帶有翅膀的,叫草蛉。我仔細找的話,常常能在陽台發現蚜獅的蹤跡,但很少看到成熟後的草蛉,大概都飛走了,或是隱身在陽台綠葉中。

Three empty eggs of Green lacewing (Chrysopa sp.) on a leaf of Chinese treeberry are noted on my balcony in Taichung, Taiwan. 三顆草蛉的空卵殼,分別以一根細絲立在楊梅的葉背上,像是一排氣球。

Low-key lighting enhances the silks between eggs and the leaf. 晚上比較少散射光,用閃光燈拍,更能看清楚細絲黏在葉子的地方。

Faint orange stripes are inside the black eyes. 複眼內側隱約可見橙色斑。
