My first breeding success of the year - Phyllonorycter roboris.
I made a special effort last October to try to find mines of this relatively scarce species. In Worcestershire it has been recorded fairly regularly as a leaf mine at the Wyre and Monkwood. There are also older records from the Knapp and the Old Hills.
I found the mines to be extremely difficult to find in Monkwood last year - I managed one intact mine in a two hour search. Things were slightly better in the Wyre at Lodge Hill where I found 4 mines in a similar time period. The mines are reasonably easy to differentiate from the other Oak feeding Phyllonorycters. They are large (15mm+ long) underside mines usually with a smooth surface.
I brought the mines indoors in late January and one from the Wyre produced the rather beautiful adult photographed here. Oliver Wadsworth
