Leucoptera laburnella (Stainton, 1851)
[Lepidoptera: Lyonetiidae]

Laburnum Leaf Miner


Cemiostoma laburnella Stainton, 1851. Cat. Suppl.: 11.
Cemiostoma wailesella
Stainton, 1858. Weekly Int. 4: 44.
Leucoptera laburnella
(Stainton, 1851).


Leaf-miner: An irregular gallery filled with greenish frass, leading to a circular or oval blotch with blackish frass arranged in a spiral fashion (British leafminers).

The very first part of the mine is a densely contorted corridor of about 2 mm long, that quickly turns brown. It is followed by a more or less straight corridor of c. 10 mm, entirely filled with greyish green frass. This suddenly widens into a round blotch that during its expansion overruns the earlier corridor and in the end may occupy half of a Laburnum leaflet. The frass, greenish at first, black later, is deposited in the bloth in roughly concentric arcs, glued to the upper epidermis. Pupation external, exit slit in upper epidermis (Bladmineerders van Europa).

The mine is also illustrated in UKMoths.

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 British leafminers, UKMoths and Bladmineerders van Europa.

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

The larva is described by Patocka (2000a) and Patocka and Turcani (2005a); rear half of abd. 8 scabrous (difference with L. genistae) (Bladmineerders van Europa).

The pupa is also described in British leafminers and UKMoths.

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

Distribution in Great Britain & Ireland: Widely distributed and fairly commonly throughout much of the British Isles (UKMoths) including Anglesey, Bedfordshire, Caernarvonshire, Cambridgeshire, Cardiganshire, Denbighshire, Dorset, Durham, East Cornwall, East Norfolk, East Ross, East Suffolk, Easterness, Edinburgh, Flintshire, Glamorgan, Haddington, Hertfordshire, Kincardineshire, Leicestershire, Linlithgow, Merionethshire, Middlesex, North Aberdeen, North Devon, North Somerset, Northumberland South, Pembrokeshire, Shropshire, South Aberdeen, South Wiltshire, South-east Yorkshire, South-west Yorkshire, Stafford, Surrey, Warwickshire, West Gloucestershire, West Lancashire, West Norfolk, West Ross, West Suffolk, Westmorland and Worcestershire (NBN Atlas). It tends to inhabit suburban areas where Laburnum is grown in gardens (UKMoths).
