Ectoedemia heckfordi van Nieukerken & Laštuvka, 2010. ZooSys.

Leaf-miner: The mines are invariably near the edge of the leaf and are rather like E. albifasciella (which is rarely nearly the edge) - but the early mine is more contorted and the mature mine is a good deal bigger (British leafminers).

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 green and there are two frass lines (British leafminers).

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

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

Hosts in Great Britain & Ireland:

Quercus petraea Sessile Oak British Wild Flowers by John Somerville et al. British leafminers
Quercus robur Pedunculate Oak British Wild Flowers by John Somerville et al. British leafminers
