With the sun still shining and no thunder materialising I decided to make the trip up to Warton Crag again in a last-ditch effort to see the Pearls. After climbing slowly up the crag, using the easier paths this time, I found myself on the terrace below the trig point, where on Sunday we had seen the SPBFs. I managed a few shots of frits as they nectared with wings open. They all looked fresh and energetic and indeed they all turned out to be SPBFs but I was very pleased to see them.
There were many Small Heath around which did their best to distract me from my quarry; I watched a pair fluttering together for a good ten minutes before evidently deciding they were incompatible and parted company.
Several moths came to my notice: Mother Shipton (smaller than I expected), Speckled Yellow, Brown Silver-line, Silver Y.
The Wall butterfly as very active and although it kept landing on the stones it never let me get on its 'sunny' side. Just as I decided to call it a day, my first female Common Blue of the year arrived, fluttering low over the vegetation.
