Coleophora badiipennella (Duponchel, 1843)
[Lepidoptera: Coleophoridae]

Pale Elm Case-bearer


Ornix badiipennella Duponchel, 1843. Hist. nat. ent. Fr. Suppl. 4: 346.
Coleophora badiipennella
(Duponchel, 1843).


Leaf-miner and case-bearer: The larva initially forms a gallery along the midrib, which then goes out along a vein. The end of this gallery is then excised to construct the first case. It then feeds close to this and makes several small mines (British leafminers).

The final case is a small, laterally compressed, squat, spatulate leaf case of 5-6 mm. The dorsal keel has some serrations, remnants of the leaf margin out of which the case was cut. The rear is twovalved, and remarkably broad. The mouth angle is 0-10°.

The description and illustration of the final case in Emmet et al. (1996a) is not quite clear. They depict a rather slender case, and state that the mouth angle is 30°. But, as the only illustration in the other literature that would agree with the British badiipennella, they refer to Hering (1957a, fig. 701): this illustration, however, has no resemblance to their own figure, and has a mouth angle of c. 0°.

Emmet et al. write that the larva begins its life by making a gallery of 10-15 mm that runs from the midrib along a side vein; out if this mine the first youth case is excised (Bladmineerders van Europa).

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).

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 by Nigel Whinney. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.

Time of year - larvae: September - May (British leafminers).

Time of year - adults: The adults fly in June and July and occasionally come to light.

Distribution in Great Britain & Ireland: Locally distributed throughout much of England (UKMoths) including Bedfordshire (VC30), Cambridgeshire (VC29), Cheshire (VC58), Derbyshire (VC57), East Kent (VC15), East Suffolk (VC25), Huntingdonshire (VC31), North Essex (VC19), North Somerset (VC6), North Wiltshire (VC7), Shropshire (VC40), South Wiltshire (VC8), Staffordshire (VC39), West Suffolk (VC26) and Worcestershire (VC37) (NBN Gateway) and the Channel Is. (Karsholt and van Nieukerken in Fauna Europaea). It occurs around the edges of woodland and prefers saplings to mature trees (UKMoths).
