I found a leaf mine on a leaf of snowberry (Symphoricarpos) growing in the hedge at Balcombe Green that separates the lane from Red Barn Field.
It was made by the larva of an Agromyzid fly, Aulagromyza cornigera, and the grub has already fed up and left the mine. It addition to its shape, identification is made easier by the fact that its larval stages are spent in April and early May.
I also found an Oecophorid micromoth, the sulphur-underwinged tubic, Esperia sulphurella on a nettle leaf. This is a widespread species and, I think, the name ‘tubic’, comes from the fact that the larvae, which feed on dead wood, conceal themselves in an under bark tube of spun silk.
