Leaf-miner: Initially the larva mines the leaflet, leaving a central line of black frass, then grazes the leaflet tips externally, causing withering (British leafminers).

The young larva mines a fine leaf segment completely out, leaving a black, central frass line. Older larvae live free on the the upperside of the leaves, causing window feeding (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).

Head and feet yellowish brown; body olive green with three length rows of whitish pinacula (Bladmineerders van Europa).

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

Larva pupates in an white ribbed cocoon (Bladmineerders van Europa).

Adult: The adult is not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).

Time of year - larvae: June - July (British leafminers).

Time of year - adults: Currently unknown.

Distribution in Great Britain & Ireland: Widespread in Britain including Easterness (VC96), Leicestershire (VC55), South Aberdeenshire (VC92), Stafford and Warwickshire (NBN Gateway). First found in Aviemore in 1966. It is fairly common on the riverbanks and verges in the Highlands (British leafminers). See also British leafminers distribution map.
