Leaf-miner: Blotch mine, frass in long threads. The mine can be confused with that of the beetle Orchestes pilosus, but the mine of O. pilosus is darker and smaller when mature. The frass of E.subpurella is also typically 'spaghetti' like in appearance (British leafminers, as Eriocrania). Oviposition within the leaf tissue, some 2 mm away from the leaf margin. The mine begins as a narrow corridor of c. 5 mm, largely filled with granular frass. This corridor abruptly widens into a large, dirty-whitish, full depth blotch that lies against the leaf margin and usually runs over the previous corridor. Frass here in long threads. Often several larvae in a mine after fusion of the original solitary mines. When the mines are made the foliage still is very tender, and the mines quickly wither away; they cannot be found later in summer. Probably for he same reason the oviposition site almost always is a small hole. Pupation in the ground (Bladmineerders van Europa). The mine is also illustrated in UKMoths (as Eriocrania subpurpurella). 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).Larva white, head pale brown (British leafminers, as Eriocrania subpurpurella). The larva is also 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 (as Eriocrania subpurpurella). The species is included in mothdissection.co.uk. Hosts in Great Britain and Ireland:
Hosts elsewhere:
Time of year - larvae: May - June (British leafminers, as Eriocrania). Time of year - adults: This species is quite an early flyer, being on the wing in April and May, and despite being generally diurnal, is often found in light-traps at night (UKMoths (as Eriocrania subpurpurella). Distribution in Great Britain and Ireland: Common throughout the whole of Britain except the very north of Scotland (UKMoths, as Eriocrania) including Anglesey, Bedfordshire, Breconshire, Buckinghamshire, Caernarvonshire, Cambridgeshire, Carmarthenshire, Cheshire, Cumberland, Derbyshire, Dorset, Dumfriesshire, Dunbartonshire, Durham, East Cornwall, East Kent, East Norfolk, East Ross, East Suffolk, East Sussex, East Sutherland, Elgin, Flintshire, Forfar, Glamorgan, Haddington, Herefordshire, Hertfordshire, Huntingdonshire, Isle of Wight, Kincardineshire, Leicestershire, Linlithgow, Merionethshire, Mid-west Yorkshire, Middlesex, Monmouthshire, Montgomeryshire, North Aberdeenshire, North Devon, North Essex, North Hampshire, North Lancashire, North Northumberland, North Somerset, North Wiltshire, North-east Yorkshire, North-west Yorkshire, Northamptonshire, Pembrokeshire, Shropshire, South Aberdeenshire, South Devon, South Essex, South Hampshire, South Lancashire, South Northumberland, South Wiltshire, South-east Yorkshire, South-west Yorkshire, Stafford, Stirlingshire, Surrey, Warwickshire, West Cornwall, West Gloucestershire, West Kent, West Lancashire, West Norfolk, West Ross, West Suffolk, Westmorland, Wigtownshire and Worcestershire (NBN Atlas). Also recorded in the Republic of Ireland and Northern Ireland (Fauna Europaea and National Biodiversity Data Centre Map).
