The Red Admiral and Painted Lady records were all trapped at night.
Other trappers on St Agnes caught Palpita vitrealis, Gems, Four-spotted Footman, Scarce Bordered Straw etc. in addition to the above records.
9 nights in 2008 with 2 traps on St Agnes yielded only 23 Rush Veneer,but 8 Vestal, 37 Gems and 195 White-specks and several rarer species.
It's interesting to speculate which of our south coast 'migrants' are true migrants or transient residents or permanent residents. 37 Gems and 195 White-specks possibly showed residency in 2008, but lower figures in 2009 show the effects of a cold winter?
