Ectoedemia quinquella (Bedell, 1848)
[Lepidoptera: Nepticulidae]

Five-spot Pigmy


Microsetia quinquella Bedell, 1848. Naturaliste 29: 251.
Ectoedemia quinquella
(Bedell, 1848).


Leaf-miner: A small, contorted gallery, in 'green island' often many in one leaf. (British leafminers).

Contrary to the other Ectoedemia's on oak, the egg is deposited on the leaf underside, near a vein. The larva makes a strongly contorted corridor, that is not appreciably widenend at its end; often a number of mines in a leaf. Puption 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).

Larva yellow, with green gut-line and dark brown head. Early instars have black ventral plates, which are not present in the final instar British leafminers. Yellow with a dark head; ventral plates conspicuous, black (Gustafsson and van Nieukerken, 1990a). They can easily be confused with the larvae of E. rufifrontella (van Nieukerken ao, 2010a) (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 by Rob Edmunds. The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
