These are the records since 2000 for all of yorkshire (all of single moths) in all five VCs:
... and some of these are from inexperienced or unreliable observers so the real totals may be less. In the Harrogate area we have 33 records, but only one since 1998. Most recent ones are from VC63 but it does turn up in other places. Forgive my scepticism with this species, but several ones I've chased up have been Square-spot Rustics.
Anyway, it's great that you have a hot spot in your area, so I shall be much less sceptical about records from the Halifax district!!
