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 male and female genitalia are illustrated by the Lepidoptera Dissection Group.

Hosts in Great Britain & Ireland:

Betula       British leafminers
Betula       Pitkin & Plant
Betula       UKMoths

Hosts elsewhere:

Betula pendula Silver Birch British Wild Flowers by John Somerville et al. Bladmineerders van Europa

Time of year - larvae: May - June (British leafminers).

Time of year - adults: May and June (UKMoths).

Distribution in Great Britain & Ireland: Well distributed across mainland Britain, but fairly localised, this species is probably overlooked (UKMoths) including Bedfordshire (VC30), Buckinghamshire (VC24), Cheshire (VC58), Derbyshire (VC57), East Ross (VC106), East Suffolk (VC25), Herefordshire (VC36), Shropshire (VC40), South Aberdeenshire (VC92), Staffordshire (VC39), Surrey (VC17), Warwickshire (VC38), West Gloucestershire (VC34), West Kent (VC16), West Suffolk (VC26) and Worcestershire (VC37) (NBN Gateway).
