Leucoptera lathyrifoliella (Stainton, 1866)
[Lepidoptera: Lyonetiidae]

Southern Bent-wing


Cemiostoma lathyrifoliella Stainton, 1866. Entomol. Ann.: 170.
Leucoptera lathyrifoliella
(Stainton, 1866).


Leaf-miner: A blotch mine is formed with a small area of browning of the leaf around the egg (British leafminers).

Flat, upper-surface, oval blotch without a preceding gallery, with clear amounts of greenish frass. Sometimes more than one mine in a leaflet, that can merge. Pupation outside the mine (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).Widest in the metathorax; segment limits deeply constricted. Head shining pale yellow (darker in earlier instars), mouth parts light brown. Prothoracic plate divided, obscure, with a pair of darkened spots anteriorly. Thoracic feet small, shining pale yellow like the body (Emmet, 1985a) (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 genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).

Distribution in Great Britain & Ireland: Britain including Isle Of Wight and South Devon (NBN Gateway) and Harlech, Merionethshire. A very local mainly coastal species, tending to be confined to cliffs and undercliffs (British leafminers). See also British leafminers distribution map.
