Morley’s Final Catalogue: Not listed.

Recent Status: This species is becoming more regularly recorded in Suffolk as part of the species spread in Britain since the first record in 1974.

Life Style: The species is double or treble brooded with the adult moth hibernating. The larvae mine leaves of Populus x-canescens and P. alba, preferring sucker or sapling growth. They pupate in a cocoon under a protective membrane at the edge of a mined leaf.

Identification: Phyllocnistis species are small white winged species with a smooth scaled head. They have a sharp small terminal black dot with two dark striae emanating from it through the apical cilia. They all have four or five costal and three dorsal dark striae. The second costal and first dorsal striae usually form a complete fascia. The area between the first and second dorsal striae is shaded. In P. xenia this is yellow, orange or ochre with the colour often extending further towards the costa and basally of the first dorsal stria. In P. unipunctella this area has limited yellow but has an oval dark patch. It also has dark shading centrally in the wing and may have it at the base of the dorsum, before the first dorsal stria and a single central longitudinal line. P. saligna has a uniform yellow and dark mixed patch and a double dark central longitudinal line. In all species these markings may be reduced.
The larvae of P. xenia mine a highly sinuous gallery with a dark central line of frass. This is particularly narrow when the underside is mined. More Info
