British Insects: the Genus Phyllonorycter (Lepidoptera-Gracillariidae)
Synonyms: Phyllonorycter deflexella (Stainton), Phyllonorycter pomonella auct.
Associated with trees and shrubs. On Rosaceae; Prunus (certainly P. spinosa, P. domestica, and perhaps other species and hybrids as well?).
Larvae. The larvae mining in leaves; in the under-side. Found in July, or September to October.
Adults. Face white. Head ochreous and fuscous. Thorax bright saffron yellow (with a shining white central line).
Wing-span 7–8 mm. Forewings golden ochreous; not suffused throughout with fuscous; with a well defined basal streak (this bent slightly downwards, narrow, traversing about a third of the wing). The basal streak pale; straight, neither markedly long and slender nor sinuate (slightly down-curved); dark-edged above. Forewings with well defined pale strigulae (four costal, three to four dorsal). Costal strigulae 4. Dorsal strigulae 3–4 (two discrete, the pair inside the fringe line somewhat confluent). Forewings with the first costal strigula approaching a dorsal one at an acute angle; with one transverse pale fascia (sometimes, via the first costal and first dorsal strigulae), or without transverse pale fasciae. Hindwing cilia whitish to light brown. Posterior tarsi whitish, without dark spots.
Adults abroad May and August.
