Being presented last night with a free ticket for a visit to the Olympic Park today placed me in a dilemna this morning. Should I join the mass sporting fraternity in their hour of need or maximise another beautiful sunny day in adding to my tally of Betula with no medals in prospect. Of course I did the latter! This weekend resulted in two very contrasting BrH days. Betula seemed very active at the three sites I visited on Saturday. I managed to confirm five individuals, four atop the ashes and one glorious female at ground level. Another beautiful morning today Sunday gave me high expectations of further sightings but alas it was not to be. All seemed quiet on the Betula front despite visiting three further regular BrH haunts.
This experience is not a first for me but an example of the many challenges put in the way of us mere human mortals by this most fascinating of butterfly species.
