Elachista bisulcella (Duponchel, 1843)
[Lepidoptera: Elachistidae]

Yellow-tipped Dwarf


Lita bisulcella Duponchel, 1843. Stett. ent. Zeits: 203.
Elachista bisulcella
(Duponchel, 1843).


Leaf-miner: Mine a descending and widening corridor, in the end an elongate blotch that may occupy the entire width of the leaf. The mine contracts somewhat, narrowing the leaf. Frass in some elongate lumps in the centre of 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).

The larva of bisulcella has body dull grey green with a narrow dorsal line; head pale brown with darker marking; prothoracic plate dark brown, irregularly divided (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 Mark Cubitt. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.

Comments: Festuca arundinacea is treated as Schedonorus arundinacea (Tall Fescue) by Stace (2010).
