Elachista cinereopunctella (Haworth, 1828)
[Lepidoptera: Elachistidae]

Grey-spotted Dwarf


Tinea cinereopunctella Haworth, 1828
Biselachista cinereopunctella
(Haworth, 1828)
Elachista cinereopunctella
(Haworth, 1828).


Leaf-miner: Mine generally descending from the leaf tip. The mine may occupy the space between leaf margin and midrib, but may also occupy the entire width of the leaf. Most frass accumulated in the oldest part of the mine. Pupation external; the pupa is attached to the leaf without a cocoon (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 Steuer (1978a). Head and prothoracic shield dark brown. Body yellowish white, with a pair of orange red latero-dorsal length lines; ventrally another such line, medially (Bladmineerders van Europa).

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

Described by Patocka (1999a), Patocka and Turcáni (2005a) (Bladmineerders van Europa).

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