Hitherto a very rare species in Belgium. As with other Psychids, this species is undoubtedly underrecorded and more than likely has a bigger distribution in our country.
Native
Wingspan 12–16 mm. Males have wings, females are apterous. Male butterflies are reminiscent of Taleporia tubulosa but are significantly smaller.
The subgenus Siederia differs from the subgenus Dahlica due to the presence of an epiphysis (for cleaning the antenna) on the foreleg tibia, otherwise wing shape, pattern en venation are similar.
Present from April/May and after hibernation till March. Body grey with yellowish hues, head black, neck shield black.
Lenght 5–8 mm, width 1,5–2,6 mm. The slender triangular case is covered with fine grains of sand and small particles of plants, lichens, algae and larval excrements.
The larva pupates in the case. Adults come to light.
The adults fly in spring, depending on climate conditions: from March till May.
Forests, gardens, and parks.
