As an illustration of how dodgy it can be to claim records of Hoary Footman without looking at the hind-wings (which are white), I had this candidate in the garden last night but it proved to be a worn Scarce Footman when the hind-wings were checked (creamy yellow). Scarce Footman can fade quite significantly as its flight season progresses. Luckily it doesn't usually last much beyond the third week of August and Hoary Footman can be found into October, so there's less of a problem as the summer goes on. Up here in mid-Bucks I didn't start to see Hoary until 2014 and still only get two or three per year, so while it seems to have a toe-hold locally it is still far from being common.
