Parornix anglicella
Parornix anglicella is a moth of the family Gracillariidae found in Asia and Europe. It was described in 1850, by the English entomologist Henry Tibbats Stainton, from a specimen from Lewisham, Kent.
Description
The wingspan is 9–11 mm. The head is ochreous-whitish mixed with fuscous. Palpi white, apex of second joint and median band of terminal dark fuscous. Forewings are dark fuscous, irrorated with whitish; numerous costal strigulae, a spot in middle of disc and another posteriorly, and suffused dorsal strigidae interrupted by two blackish spots white; a black apical dot; cilia with three entire dark fuscous lines. Hindwings are grey. The larva is pale greenish-grey; dorsal line darker; spots pale; head pale greenish-brown; segment 2 with four black spots.Biology
Adults are on the wing in two generations in April and May and again in August.;Ovum
Eggs are laid on the underside of the leaves of hawthorns, but have also been recorded on medlar, rowan, wild service tree and strawberries.
;Larvae
Feeding starts in a gallery in the epidermis, which leads to a leaf margin and develops into a blotch in the second instar. In the next phase the larva eats through to the upper epidermis, puckers the leaf and the epidermis turns brown and the frass is at one end of the mine. It is distinguished from a Phyllonorycter oxyacanthae mine, by the smaller size and the lower epidermis stays green. After leaving the mine two or more cones are made by folding the leaves downwards in the manner of a Caloptilia rather than other Parornix. Occupied mines can be found from July to September.
;Pupa
The pupa is pale-yellow-brown in a whitish cocoon, sometimes spun under a narrowly folded edge of a leaf, or in leaf-litter or an old bird's nest. Pupation takes place in July–August and September to late-April.
