Monochroa arundinetella (Stainton, 1858)
[Lepidoptera: Gelechiidae]

Sedge Neb


Gelechia arundinetella Stainton, 1858. Entomol. Ann.: 91
Monochroa arundinetella
(Stainton, 1858).


Leaf-miner: Rather narrow, long, corridor, of which the course largely is dictated by the venation; the mine may change direction (up/down). The larva may leave its mine and restart elsewhwere. Pupation within the mine; pupa in a white cocoon, just above the waterline (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).

Whitish; head black; pronotum laterally with a black spot (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 not illustrated by the Lepidoptera Dissection Group (check for update).

Comments: Hering (1957a) and older authors also mention Phragmites australis [as a host]; this is not repeated by later authors, and possibly stems from confusion with other species (Bladmineerders van Europa)

Hosts in Great Britain & Ireland:

Cyperaceae        
Carex acutiformis Lesser Pond-sedge British Wild Flowers by John Somerville et al. Pitkin & Plant

Time of year - larvae: March - May (Hering, 1957).

Time of year - adults: Currently unknown.
