Roeslerstammia erxlebella (Fabricius, 1787)
[Lepidoptera: Roeslerstammiidae]

Copper Ermel


Alucita erxlebella Fabricius, 1787. Mant. Ins.: 256.
Roeslerstammia erxlebella
(Fabricius, 1787).


Leaf-miner: The larvae feed on the leaves of lime and birch, mining the leaves when young (UKMoths).

Oviposition at the leaf upperside. Mine a short, irregular, full depth corridor, always at the leaf margin, generally in the tip of the leaf. Frassly broadly scattered. The older larva lives free on the leaf (Bladmineerders van Europa).

The mine is also illustrated in British leafminers.

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 Duncan Williams) and the Encyclopedia of Life. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.

Time of year - larvae: July, September - October (British leafminers).

Time of year - adults: Two generations, at least in the south of the range, with adults on the wing in May and June and again in August and September (UKMoths).
