Took Sue to Twickenham for the last day of her convention. After dropping her off I went to RichmondPark and found a clump of thistles rich with Painted Ladies, Peacocks (above), Meadow Browns, and Large Whites. Also saw a Blue, assume Common, but it moved off too quickly to be sure. Then headed for Maidenhead in search of a White-letter Hairstreak. No luck at the first site, so went to Cliveden House, a National Trust property, formerly home of the Astors, famous for Profumo Affair. In the garden I found a Purple Hairstreak (below). No new species, but a fun day out. We ended the day with Oscars fish and chips and watched the last of the swimming world cup events.
