Flame Carpet - an unexpected summer visitor

The flight time of the Flame Carpet is generally quoted as May to August which ties in with my records which sometimes run through to early September with my last record this year on 4th September. It was quite a surprise therefore to find a Flame Carpet in the moth trap this morning. 
It's in good condition suggesting it has emerged in recent days. Studies have shown that the first emergence dates for some species are getting earlier and the last dates later and the Flame Carpet has been quoted as an example of this in Irish phenology studies but 2 months is well outside the norm.
