Hertfordshire Notes:
Widespread, but local. Probably under-recorded. Young caterpillars mine the underside of young leaves of clovers and can be difficult to spot, though as the larva gets more mature the mines become full-depth and can become visible from above without needing to turn over every single leaf.

Middlesex Notes:
Local and usually scarce, though the leaf mine, on Red Clover Trifolium pratense, is likely to be very much overlooked.

	Mine: Either the leaf or a good photograph required
