Description
editThe wingspan is 9.5–13 mm.[2] The forewing is cream-coloured with distinct white longitudinal stripes and with oblique streaks and scattered fuscous scales. Certain identification requires examination of genitalia preparations. Adults are on wing in June and July.[3]
Eggs are laid on the flowers of yarrow (Achillea millefolium) and sneezewort (Achillea ptarmica).[4]
- Larva
The early instars feed from early September on the withering flowers and seeds.[5]

The genus Coleophora was raised by the German entomologist Jacob Hübner in 1822. The name refers to a sheath, i.e. to carry, from the portable case the larvae make. The moth was named argentula by the English entomologist James Francis Stephens in 1834, from a specimen found near London, England. The species name comes from argentum – the silver streaks along the veins on the forewing, which are in contrast to the ochreous ground colour.[5][6]
