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 larvae mine the leaves of brambles (Rubus) species.

Description

The wingspan is 7–8 mm. Adults are brownish with a slight metallic sheen. Forewings ochreous-yellow; costa anteriorly narrowly, posteriorly broadly suffused with dark purplish-fuscous; termen suffused with dark purplish-fuscous; a dark fuscous tornal dot. Hindwings rather dark grey.[2] They are on wing from May to June and again in August.[3]

Ovum

Eggs are laid on the upper surface on a bramble leaf, especially Rubus fruticosus.[4]

Larvae

The larvae feed on European dewberry (Rubus caesius), Rubus canescens, Armenian blackberry (Rubus armeniacus), blackberry (Rubus fruticosus), Rubus grabowskii, Rubus hypargyrus, raspberry (Rubus idaeus), evergreen blackberry (Rubus laciniatus), Rubus macrophyllus, Rubus nemorosus and stone bramble (Rubus saxatilis). They mine the leaves of their host plant. The mine has the form of a short corridor that widens into a long, elliptic blotch. The blotch is upper-surface and whitish to yellow-brown. The inside of the mine is lined with silk. The frass is ejected out of the mine through an opening in the underside of the mine. Larvae are pale green with a blackish-grey head, prothoracic plate and small anal plate. Occupied mines can be found in June and again from September to March.[5][6]

Pupa

Pupation takes place within the mine and the pupa is not enclosed in a cocoon.[5]

Taxonomy

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. The moth was later placed in the genus Tischeria and than Emmetia. It is now in the genus Coptotriche. The specific name, marginea, from the Greek margineus - of a margin or an edge, from the dark costa and terminal margin of the forewing.[7]
