Leaf-miner: The mine formed in the leaf-veins and midrib leads to an oval blotch (British leafminers). When fully fed, the larva cuts out an oval case, in which it descends to the ground and pupates (UKMoths).

The mine begins in one of the more heavy veins of a leaf. Boring in the vein the larva descends towards the midrib. Often in this process the larva moves from one thick vein to another by way of a hair-thin transverse corridor. Once in the midrib the larva descends, not rarely even for one or two cm into the petiole (one can see that by cleaving a petiole). Finally the larva returns into the leaf by way of the midrib, and makes a short, full depth, quickly widening corridor with a clear central line of frass. In the end an oval excision of made of about 2 x 5 mm, in which the larva drops to the ground (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).

Described by Patočka and Turčáni (2005a) (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.

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

Time of year - adults: The adult moths fly in a single generation from late May to July, often in sunshine around alder branches (UKMoths).

Distribution in Great Britain & Ireland: The moth is widespread and locally common throughout England, Wales and parts of Southern Scotland (UKMoths) including Banffshire, Bedfordshire, Brecon, Cambridgeshire, Cardiganshire, Carmarthenshire, Cheshire, Cheviotland, Denbighshire, Derbyshire, Dumfrieshire, Dunbarton, Durham, East Cornwall, East Kent, East Norfolk, East Ross, East Suffolk, Glamorgan, Haddington, Hertfordshire, Huntingdonshire, Isle of Wight, Kincardineshire, Merionethshire, Middlesex, North Devon, North Ebudes, North Hampshire, Northumberland South, Pembrokeshire, Shropshire, South Aberdeen, South Wiltshire, South-west Yorkshire, Stafford, Stirling, Warwickshire, West Cornwall, West Norfolk, West Suffolk, Westmorland, WIgtownshire and Worcestershire (NBN Atlas).
