Scrobipalpa ocellatella (Boyd, 1858)
[Lepidoptera: Gelechiidae]

Beet Moth


Gelechia ocellatella Boyd, 1858. Ent. Weekly Intell. 96: 143.
Scrobipalpa ocellatella
(Boyd, 1858).


Leaf-miner: Young larvae bore in the midrib, later they mine the leaf from a web spun over of the leaf (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).

Grey green, with some vague reddish brown length lines; head and prothoracic plate light brown; rear margin of the pronotum black brown; anal plate grey green (Jansen, 1999a; Bland et al., 2002a; Gómez de Aizpúrua, 2003a) (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 genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.

Comments: In the literature also recorded on Atriplex portulacoides, Salicornia europaea, Suaeda maritima and Suaeda vera. However, according to Maurice Jansen (in litt.) these associations are very dubious (Bladmineerders van Europa).
