Hertfordshire Notes:
Rare or overlooked. There are only two Hertfordshire records: the first was from the Sandridge area (Griffith, 1890) and is not mapped as the precise locality is unclear. The next was not until 21st October 2006, when I found a vacated mine on Sweet Chestnut and, after searching, an associated pupal cocoon, at Chorleywood Common.

Middlesex Notes:
Rare or overlooked. Our single record is from Osterley Park in 1987. It may still be present in Middlesex and should be searched for.

	Mine: Either the leaf or a good photograph required
