Sutton & Beaumont, 1989: The first County records since Porritt (1883-86) occurred at Spurn (VC61) in 1984 and a second locality has been found in 1988. Porritt has York as the only locality but he says that the specimens were much larger than those in the South and the female was bright yellow. He comments on this as a distinct variety and possibly a different species. No mention of a form matching this description is made by Skinner (1984) or de Worms (MBGBI 9). It seems strange that such an observation should pass without comment.
Argus 47, 2001-04:
VC65. Hutton Conyers, 31.7.2002, 8.8.2004 (CHF); Magdalen Wood, 14.7.2004 (CHF, JCW, SPW). NEW VICE-COUNTY RECORD.
2012 (CHF): The "bright yellow" form described by Porritt is surely f. unicolor (Bankes) which in fact is described in MBGBI 9 and also by Waring and is not uncommon in the county. This is yet another Footman which has recolonised the county, initially at Spurn then spreading north-west quite fast so that now it can be found all over the county though it is still a little uncommon in the west. Numbers in mature broadleaved woodland can occasionally be spectacular eg 1310 trapped on 13.8.2009 at Newtondale in VC62 - a quite unprecedented number!
