Eriocrania salopiella (Stainton, 1854)
[Lepidoptera: Eriocraniidae]

Small Birch Purple

Micropteryx salopiella Stainton, 1854. Ins. Brit. 3: 44, t. 9 fig. 4.
Eriocrania salopiella
(Stainton, 1854).

Leaf-miner: The early gallery starts in the centre of the leaf. It is a linear track which widens to a large blotch at the leaf edge, with frass in long threads (British leafminers).

Corridor, generally beginning in the neighbourhood of the midrib, rather gradually widening into a very large blotch. Frass in long threads. Pupation in the ground (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 is illustrated in 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

Also recorded in the Republic of Ireland and Northern Ireland (Karsholt and van Nieukerken in Fauna Europaea). See also Ireland's NBDC interactive map.

Distribution elsewhere: Widespread in continental Europe including Czech Republic, Danish mainland, Finland, French mainland, Germany, Latvia, Norwegian mainland, Russia - North, Sweden and The Netherlands (Karsholt and van Nieukerken in Fauna Europaea).
