General comments:
Very local and perhaps rare. There has been past confusion of this species with that which we now call blancardella discussed under that species. Just to further confuse the situation, a supposed mine of P. mespillella in a Wild Service leaf from Horsenden Hill produced an adult P. hostis. The need to rear adults for positive identification is emphasised.

	Determination by Genitalia Examination Required

	Mine: Moth needs to be reared and, in some cases, possibly dissected.
