Species Account


Most records are of leaf-mines.

Sutton & Beaumont, 1989: Widespread and common throughout all five vice-counties.

2013 (CHF): Widespread and common across the county. Like all species mining hawthorn leaves, care must be taken in identification as not all mines are typical and it can be mistaken for several other species. The egg can be laid anywhere on the leaf, either upper or lower sides. The mine starts with a slender corridor with relatively broad continuous frass leaving a clear margin at either side. The corridor then winds freely through the leaf before changing abruptly, often with a change in direction and widens into a blotch that mostly lies along the leaf margin. The larva is colourless to pale green.
