Cornish Flat-body

Agonopterix kuznetzovi Lvovsky, 1983. Ent. Obozr. 62 (3): 594-595.

Leaf-miner: Short, gradually widening, brown, corridor, 9-13 mm long and 0.5-2 mm wide. At he start of the mine a small lower-surface hole, lined with silk, through which frass is ejected. The older larva lives free in a spinning under the leaf or, even later, in a leaf that is spun upwards into a pod (Bladmineerders van Europa).

The larva feeds on saw-wort, initially mining the leaf and later feeding on the upper cuticle, causing windows in the leaf (UKMoths).

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 young larva has a black head and prothoracic plate, a pale green body with cocncolorous anal plate and darker dorsal line. See Harper et al. (2002a) for a description of the free-living larva (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 species is included in
