Kessleria saxifragae (Stainton, 1868)
[Lepidoptera: Yponomeutidae]

Highland Ermel


Zelleria saxifragae Stainton, 1868. Trans. ent. Soc. Lond.: 139.
Kessleria saxifragae
(Stainton, 1868).


Leaf-miner: The leaf rosette is covered by several larvae with a spinning, under which each larva mines out a few leaves. Sometimes a leaf contains one or a few large frass pellets. Pupation 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).

Head and prothoracic plate black. Body spindle-shaped, dull olive green with a slightly darker dorsal line; reddish brown markings laterally on each segment; venter green (Agassiz, 1996a). The larva, illustrated on www.lepiforum.de (2009) looks rather different (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 not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
