247 Tinea trinotella
Thunberg, 1794Wingspan 12-18 mm.
This small greyish-buff moth has three dark spots on the forewing, which give rise to its scientific name. It also sports a yellowish or orange head-tuft, resulting in its diagnostic appearance.
Flying at night, and often visiting light-traps, the adults are at large between May and August, with possibly two generations.
The larva lives in a portable case, and is quite common in birds' nests, where it feeds on detritus and food remains.
