A visit for Purple Emperor, at last paid off, some photos, though only after nearly treading on it, it flew the length of the track and eventually returned to the same spot and settled for about five minutes. It was eventually joined by two others though only briefly. Silver-washed Fritilleries only came to three along with two White Admirals.

Afterwards a visit to Ivinghoe Beacon only produced three dark green Fritilleris and a quick visit to Black Park three each of White Admirals and Silver-washed Fritillary.
