This South-East Asia species (Japan, China, Malaysia towards New Zealand and Australia) was discovered for the first time in Europe during 2000.
In 2007 the first observation for Belgium became known (WV), since then, this adventive species spread out and few observations became known. It's possible that the species might be established after its initial introduction.
Hitherto a very rare species in the northern part of Belgium.
Invasive In Belgium since August 2007.
This Oriental and Australasian species was probably imported into Europe by sea or air transport, firstly to Portugal where in 2000 the first specimens were recorded. From there, the species spread to several European countries. First Belgian record: Wielsbeke (OV), 2007-08-13, leg. S. Wullaert.
Wingspan 12–14 mm. The forewing is slender with the end of the wing more bending. In resting position it leads to a wavy appearance. Ground colour yellowish brown to darker red brown, with sometimes variation in colorur. Against the termen the interneural dots are present, with a more white edge. Fringe black to grey. More remarkable are the white dots at the costa. Hindwings ground colour mainly smooth white with the discal spot present, and a prominent darker area on the underside.
The adult moths come to light and sugar.
The adults can be observed in almost all months of the year.
Little is known about the life cycle. The supposed hostplant is Carex.
