.陳裕隆-黑翅蟬羽化過程
( Eclosion Process of the Huechy’s sanguine)

蟬大多在傍晚或晚上羽化，臺灣有兩種蟬在白天羽化，稀有的黑翅蟬是其一。身上的鮮紅色在自然界是警告色，牠們得以在白天羽化。常見於饅頭果、九芎樹上棲息，幼蟲於地底吸食樹根，終齡若蟲爬出地面羽化，五月的臺中大坑地區大量發生，近兩年由於環境破壞，數量已不如以往。剛羽化的個體翅膀為白色，身體為鮮紅色，翅膀完全伸展晾翅約1~2小時，翅膀、身體、背部及頭部都會由紅轉黑，這時就具備飛行及交配能力，大概完成變色之後就會交尾。這稀有物種的奇特羽化時間與體色轉變，讓人一窺豐富多變的自然界生態。

Cicadas for the most part go through eclosion during the evening or at night. There are two kinds of cicadas that eclose during the daytime. One is the Huechy’s sanguine. The red warning color on its body enables it to eclose during the day.  Frequently found resting in Breynia officialis and Lagerstroemia subcostata. The larva will suck on the roots from below and climb out when mature from the underground to eclose. Large numbers will appear in Dakeng, Taichung during May.  Due to environmental destruction in recent years, their numbers have dwindled considerably. When they first emerge, their wings are white and the bodies are red. The expansion and drying of the wings take 1-2 hours. The wings, body, back and head will then gradually change from red to black. They will then have the ability to fly and mate. Generally they mate as soon as the color changing process is completed.  The unique eclosion process and the color change of this rare species display the wonders of the natural world.
