35.138 Caryocolum junctella (Winter Groundling)
ws: 9.5-11.5mm; Jul-May, hibernates as adult; lesser stitchwort (Stellaria graminea), mouse-ears (Cerastium spp); woodland in midlands, NW.England, Wales and N.Scotland
Caryocolum junctella §1 female
ID: Keyed in MBGBI4.2 thus: thorax grey, ochreous or fuscous; fw with some orange-ochreous markings; fw with dark fuscous bar from costa to fold at ~45 degree angle with costa and meeting costa only for a short distance > C.junctella/alsinella/viscariella
These are differentiated in the key by C.junctella having frons 'silvery' as opposed to 'shining pale ochreous-grey' and on male genital features.
C.alsinella can be excluded on habitat as it is confined to sandy coasts
C.viscariella can be excluded on flight season (Jun-Jul)
Further confirmation can be found in the species descriptions given in MBGBI4.2. Only 3 species (C.proximum/junctella/tricolorella) are described as having pink bands on the fore & midtibiae; only 2 species (C.proximum/junctella) are described as having a pink tuft below the eye. C.proxima and C.viscariella do not occur as far north as Perthshire and are excluded by fw features.
