Argus 56, 2008: This is the first VC65 record since that listed by Porritt at the end of the nineteenth century. The only other recent Yorkshire record was from VC63 in 2005.
VC65. Aldbrough St. John, mine on crab apple 6.11.2008, conf. J.R. Langmaid (CHF).

2013 (CHF):An uncommon species, the larvae mining the leaves of apple. The egg is laid on the underside of the leaf. The mine is a small compact corridor between the veins, rather strongly widening towards the end to form a small blotch, mostly in a vein axil. The colour of the mine is often orange and the frass is in a broad, irregular central line. Mines can sometimes be found in green "islands".
