Gallery-like full depth mine, mainly in the base of the leaf, with
irregularly scalloped sides. Frass in the oldest part of the mine
in thick black grains; further on the mine does not contain frass
at all. In the transition between the two parts there is a hole
in the epidermis from which frass is ejected. Older larvae live
free, between spun terminal shoots (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).
Young, mining larvae green (Hering, 1957a). Older larvae dull
whitish green with five dull pink length lines. Head and prothoracic
plate black; pinacula small, black (Bland et al., 2002a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
See Patocka and Turcáni (2005a) (Bladmineerders van Europa).
The adult is illustrated in UKMoths by John Murray. The male and female genitalia are illustrated by the Lepidoptera
Stellaria uliginosa is treated as Stellaria
