Ectoedemia agrimoniae (Frey, 1858)
[Lepidoptera: Nepticulidae]

Agrimony Pigmy


Nepticula agrimoniae Frey, 1858. Entomol. Weekly Intell. 4:43.
Ectoedemia agrimoniae
(Frey, 1858).


Leaf-miner: The initial gallery is twisted and can follow the leaf edge. It contains broken linear frass. it then widens to form a blotch or gallery, with scattered frass (British leafminers).

Oviposition on the leaf underside. There starts an initially strongly contorted narrow corridor with a linear interrupted frass line. This is continued in broad corridor or elongated blotch with dispersed frass. Often a number of mines in a leaf. Pupation inside the mine, in a a violet to blackish 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).

Greenish yellow, ganglia conspicuous, brown; head brown; ventral plates absent (Bladmineerders van Europa).

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

Pupation in the mine (British leafminers).

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