Eriocrania cicatricella (Zetterstedt, 1839)
[Lepidoptera: Eriocraniidae]

Washed Purple


Adela cicatricella Zetterstedt, 1839. Ins. Lapp.: 1008.
Eriocrania haworthi
Bradley, 1966. Ent. Gaz. 17: 214.
Tinea purpurella
Haworth, 1828. Lep. Brit.: 571
Eriocrania cicatricella
(Zetterstedt, 1839).


Leaf-miner: Blotch clouded, with some green matter left in mine. Several larvae (2-4) in one mine (British leafminers).

Large full depth blotch, adjacent to the leaf margin. The mine is not completely eaten out, which gives it a greenish or off-white appearance. Frass in threads, that seem to be somewhat shorter than in other Eriocrania's. The mine harbours 2-4 strikingly hyaline larvae. Pupation in the ground. Older mines wither and wear off; in summer no trace of them is left (Bladmineerders van Europa).

The mine is also illustrated in 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).

Small, translucent white (British leafminers).

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).

Adults: The adult is illustrated in UKMoths. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.

Hosts in Great Britain & Ireland:

Betulaceae        
Betula       British leafminers
Betula       Pitkin & Plant
Betula       UKMoths

Hosts elsewhere:

Betulaceae        
Betula pubescens Downy Birch British Wild Flowers by John Somerville et al. Bladmineerders van Europa

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

Time of year - adults: The adults fly around the foodplants during April, but are not often seen (UKMoths).

Distribution in Great Britain & Ireland: Generally well distributed throughout much of mainland Britain (UKMoths) including Bedfordshire (VC30), Buckinghamshire (VC24), Derbyshire (VC57), East Kent (VC15), East Suffolk (VC25), East Sutherland (VC107), Glamorganshire (VC41), Herefordshire (VC36), North Essex (VC19), North Hampshire (VC12), Shropshire (VC40), South Wiltshire (VC8), Staffordshire (VC39), Surrey (VC17), Warwickshire (VC38), West Gloucestershire (VC34), West Kent (VC16), West Norfolk (VC28), West Suffolk (VC26), Westmorland (VC69) and Worcestershire (VC37) (NBN Gateway).
