Ectoedemia sericopeza (Zeller, 1839)
[Lepidoptera: Nepticulidae]

Norway-maple Pigmy


Lyonetia sericopeza Zeller, 1839. Isis: 215.
Ectoedemia sericopeza
(Zeller, 1839).


Samara-miner: In wing of samara, mines into the seed with a short gallery (British leafminers).

The egg of the first generation is deposited on the wing of a key. The larva makes a short, superficial corridor (sometimes only the egg is visible), leading towards the seed, that finally is eaten out. Infested samaras are prematurely shed, and should be sought on the ground. The larva of the second generation makes a short mine in the bark of a petiole, and from there penetrates a bud that is consumed from the inside out (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).

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 male and female genitalia are illustrated by the Lepidoptera Dissection Group.

Comments: Records of Ectoedemia sericopeza on Field Maple (Acer campestre) require confirmation.
