Wingspan 13–16 mm. Nemophora cupriacella is parthenogenetic, which is why males are missing.
Antennae of females are slightly longer than forewing. Basal area of forewing coppery golden, often with greenish hue. Apical area of forewing coppery red with strong gloss.
Head rust yellow, antenna base thickened with steel-blue scales and with white end. Palp hairs long, bristly protruding, yellow (this is a difference with the black-coloured palps of Nemophora violellus).
