Coleophora argentula is a moth of the family Coleophoridae, found in most of Europe, Russia and Asia Minor. The larvae live in cases and feed on the seeds of yarrow and sneezewort.
Description
The wingspan is 9.5–13 mm.{{cite web |last1=Kimber |first1=Ian |title=37.102 BF563 Coleophora argentula (Stephens, 1834) |url=https://ukmoths.org.uk/species/coleophora-argentula/ |website=ukmoths |accessdate=31 July 2019}} The forewing is cream-coloured with distinct white longitudinal stripes and with oblique streaks and scattered fuscous scales.

[[Etymology]]
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.{{cite book |last1=Emmet |first1=A Maitland |author1-link=A.
