Wingspan 8 to 9 mm. The orangey coloured adult is weakly marked in comparison to some of its congeners.
Leafmine occurs on Hawthorn (and also on Apple, Cherry and others). http://www.leafmines.co.uk/html/Lepidoptera/P.corylifoliella.htm
Found in various habitats.
Adults are at large in May and again in July/August.
Slightly unusually among Phyllonorycters, this species feeds on a fairly wide range of foodplants. Most other British species, apart from P. leucographella, are specific to one species (or at least genus) of foodplant. The mine is also unusual, in that it is found on the upperside of the leaf, and has a "double" mine within a mine, the outer mine being translucent and flecked with brown. Typical foodplants are Hawthorn (Crataegus), Apple (Malus) and various Sorbus species such as Mountain Ash. The mine can be found in July and September to October.
The species is widely scattered throughout the British Isles. In the Butterfly Conservation’s Microlepidoptera Report 2011 this species was classified as common.
Fairly frequent in Leicestershire and Rutland.
