Coleophora lineolea (Haworth, 1828)
[Lepidoptera: Coleophoridae]

Woundwort Case-bearer


Porrectaria lineolea Haworth, 1828. Lep. Brit.: 534.
Coleophora lineolea
(Haworth, 1828).


Leaf-miner and case-bearer: The mines are large and obvious on the upper side of the leaf, betraying the larva or larvae on the lower side (UKMoths).

Cases are broad and flat - being very hairy from the texture of the leaf (British leafminers).

Immediately after emergence the larva makes a full depth, quickly widening, corridor, with frass as small grains in a broad central band. Finally results in a blotch of 2 x 5 mm, from which the young case is cut. The fully developed case is a hairy, greyish brown to silver grey lobe case case of about 1 cm long, with a clearly laterally compressed end; the mouth angle is about 90°. The case is difficult to separate from that of C. ochripennella (Bladmineerders van Europa).

The case is illustrated in the Encyclopedia of Life.

Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).

The larva is illustrated in Bladmineerders van Europa.

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

Adult: The adult is illustrated in UKMoths. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.

Comments: Stachys officinalis is treated as Betonica officinalis (Betony) by Stace (2010).
