Alucita spilodesma (Meyrick, 1908)


Alucita spilodesma是多翼蛾科(Alucitidae)的成員,分布於東方區的印度、菲律賓與臺灣等地。本種的前翅共分裂為六羽枝,每羽枝皆為黃褐色底,有白色與黑色與褐色斑塊,這些斑塊組成了兩條白-黑-褐-黑-白的寬帶;後翅亦分裂為六羽枝,有白色與黑色與黃色斑塊,其中由前緣算起的第五羽枝(CuA2)有兩塊較大的黃褐色斑;頭胸腹背方以黃褐色為主,胸部有兩條黑帶,腹部各節有白點。本屬是多翼蛾科(Alucitidae)的模式屬,全世界共記錄超過100種,廣泛分布於各大地理區;然而在台灣僅記錄一種,即本種。Alucita spilodesma與其他種類可以藉由翅紋區分,因此鑑定較無難度。圖中個體產於碧綠神木。

A Brief Introduction

Alucita spilodesma represents the only species of Alucitidae in Taiwan and is characterized by its wing pattern. In the past, Alucitidae was deposited under Pterophoridae and then raised to family level. One major differece between Alucitidae and Pterophorida is that forewing and hindwing of the former are split to six parts while the later are two to three parts.

這個早就不放在Alucita下了,而且鳥羽蛾跟多翼蛾也不同科
