Leaf-miner: In the first instar the larva mines the leaves, forming short, irregular, blotch-like mines, but in later instars it lives externally, feeding in spun leaves and often twisting those of tender shoots (Bradley et al., 1973). Small, full depth mine without a definite shape; little frass. Some silk is deposited in the mine. The larva soon leaves the mine and continues feeding among spun leaves (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). Head light-brown or yellowish brown, edged with black postero-laterally, ocellar area blackish; prothoracic plate black edged with whitish anteriorly; abdomen dull dark green; pinacula distinct, black, sometimes brownish but with black bases to setae; anal plate large, black (Bradley et al., 1973). The overwintering larvae feed in a spinning on a range of herbaceous plants (UKMoths). Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples). Dull black; spines on the cremaster not bent into hooks, short, their lenght less than the distance to a ridge lying ventrad; caudal bristles only slightly thickened away from their point of origin, bent distally to form hooks (Bradley et al., 1973). Adult: The adult is illustrated in UKMoths. and the Encyclopedia of Life. The species is included in mothdissection.co.uk. Comments: Ranunculus ficaria is treated as Ficaria verna (Lesser Celandine) by Stace (2010). Hosts in Great Britain and Ireland:
Hosts elsewhere: Comments: On the continent it has been recorded on more than 200 host plants (Bradley et al., 1973). Time of year - larvae: September to May and June, the young larva spinning a hibernaculm and overwintering (Bradley et al., 1973). Time of year - adults: June and July (UKMoths; Bradley et al., 1973). Distribution in Great Britain and Ireland: Widespread in Britain including Anglesey, Bedfordshire, Breconshire, Caernarvonshire, Cambridgeshire, Cardiganshire, Carmarthenshire, Cheshire, Cumberland, Denbighshire, Derbyshire, Dorset, Dumfriesshire, Dunbartonshire, Durham, East Cornwall, East Gloucestershire, East Kent, East Norfolk, East Suffolk, Easterness, Forfar, Glamorgan, Herefordshire, Hertfordshire, Huntingdonshire, Isle of Wight, Kincardineshire, Leicestershire, Linlithgow, Merionethshire, Mid-west Yorkshire, Middlesex, North Aberdeenshire, North Essex, North Hampshire, North Northumberland, North Somerset, North Wiltshire, Nottinghamshire, Pembrokeshire, Radnorshire, Shropshire, South Devon, South Essex, South Hampshire, South Northumberland, South Wiltshire, South-east Yorkshire, North-west Yorkshire, Stafford, Stirlingshire, Surrey, West Cornwall, West Gloucestershire, West Lancashire, West Norfolk, West Perthshire, West Suffolk, West Sussex, Westmorland, Wigtoenshire and Worcestershire (NBN Atlas). Also recorded from the Channel Is. (Fauna Europaea). Also recorded from the Republic of Ireland. See also Ireland's National Biodiversity Data Centre Map). Distribution elsewhere: Widespread in continental Europe including Albania, Austria, Belgium, Bosnia and Herzegovina, Bulgaria, Crete, Croatia, Czech Republic, Danish mainland, Estonia, European Turkey, Finland, French mainland, Germany, Greek mainland, Hungary, Ireland, Italian mainland, Latvia, Liechtenstein, Lithuania, Luxembourg, Macedonia, Norwegian mainland, Poland, Portuguese mainland, Romania, Sardinia, Sicily, Slovakia, Slovenia, Spanish mainland, Sweden, Switzerland, The Netherlands and Ukraine (Fauna Europaea).
