Microsetia bedellella Sircom, 1848. Zoologist 6: 2037.
Elachista bedellella
(Sircom, 1848).


Leaf-miner: Blotch in the leaf tip; the upper side is practically flat, the lower side can turn somewhat to purple. The larva may mine 2-3 leaves (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).

Larva young yellowish white, later grey green; head light brown; pronotum with two parallel length lines, slightly widening rearwards and divided by a narrow uncoloured stripe (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 male, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group
