Tapestry moth

Japanese: モウセンガ(毛氈蛾) - モウセンガ（英語表記）tapestry moth

An insect of the family Tineidae in the order Lepidoptera. Its wingspan is about 2cm. Its wings are very long and slender, with a pointed tip on the forewing and a sloping outer edge. The hairs on the outer edge are long. The forewings are white, but the base of the third is blackish brown, and the tip is also slightly dark. The larvae are known as pests that spin threads to create passages in wool, fur and processed products and feed on them, and are also known as carpet moths. As they are transported artificially, they are indoor pests that have spread almost worldwide, but in recent years they have not been collected in Japan.

鱗翅目ヒロズコガ科の昆虫。翅の開張2cm内外。翅はひじょうに細長く，前翅頂はとがり，外縁は傾斜している。外縁部の縁毛は長い。前翅は白色だが，基部に近い1/3は黒褐色，翅頂部もやや暗色。幼虫は羊毛，毛皮およびその加工品に糸を張って通路をつくり食害する害虫として知られ，ジュウタンガ(英名carpet moth)とも呼ばれている。人為的に運ばれるため，ほとんど全世界に広がってしまった屋内害虫であるが，近年日本では採集されていない。
