Elachista rufocinerea (Haworth, 1828)
[Lepidoptera: Elachistidae]

Red-brindled Dwarf


Porrectaria rufocinerea Haworth, 1828. Lep. Brit. 4: 535.
Elachista rufocinerea
(Haworth, 1828).


Leaf-miner: The larvae feed on a range of grasses, causing whitish mines on the blades (UKMoths). Flat, translucent mine that can either run or down; the width may vary too, can be as wide as the blade. Frass few, grey, dispersed. The larva makes several mines (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).

Dirty yellow, grey green above; head brown; prothoracic plate brown with a narrow spit (Bland, 1996a) (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. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.

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