Coptotriche marginea is a moth of the family Tischeriidae, found in most of Europe.

It was named by the English botanist, carcinologist and entomologist, Adrian Hardy Haworth in 1828, from a specimen found in England.

The forewings are ochreous-yellow.The costa anteriorly narrowly, posteriorly broadly suffused with dark purplish-fuscous.

[6] Eggs are laid on the upper surface on a bramble leaf, especially Rubus fruticosus.

[8] Haworth originally called the moth Tinea marginea in 1828; the genus erected by the 18th-century Swedish botanist, zoologist and taxonomist, Carl Linnaeus in 1758.
