Stigmella poterii (Stainton, 1857).
Leaf-miner: A gallery following the leaf-edge (British
generally at the upperside of the leaf, on a vein. The mine is a
short corridor, no longer than 3 cm. Its first part is narrow and
tends to follow a vein. The second part is rather tortuous and considerably
widened, and often forms a secondary blotch. Generally only one
mine in a leaf. Mines cannot reliably been distinguished from those
of anomalella and centifoliella (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 poterii is amber yellow, head brown (whereas aenofasciella is a pale watery yellow) (British
yellow; the larva lacks a field of spinules at he rear of the pronotum,
and on the mesosternum spinulation does not only occur on the rudiment
of the foot, but also in two field obliquely in front. See Gustafsson
and van Nieukerken (1990a) for a description (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
The adult is not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera
Dissection Group (check for update).
