[Lepidoptera: Gracillariidae]

Cornish Midget

Lithocolletis desertella
Gregor and Povolný, 1949
Lithocolletis tinctoriella
Le Marchand, 1926. Amat. Papill. 3: 13.
Phyllonorycter staintoniella
(Nicelli, 1853).


Leaf-miner: Upper-surface tentiform mine (according to Hering, 1957a, mostly lower-surface in Laburnum). The mine is strongly contracted, almost folding the leaflet to a pod and concealing the mine. Pupa in the mine in a flimsy cocoon. Frass in a corner of 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).

Head pale brown, body deep yellow (Emmet et al., 1985) - a very unusual colour for a gracillariid larva (Bladmineerders van Europa).

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

illustrated by Gregor and Patocka (2001a) and Patocka and Turcani (2005a) (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).
