Or nearly...
Working according to the old adage that if you go out, you may see something, but if you stay indoors you definitely won't, I set off round my patch near Heathrow at around 1715 today, with the sun disappearing behind an ominous dark pile of cumulonimbus that the pilots out of the airport were giving a wide berth to. I headed for the area within the J14 M25 roundabout, where there is garlic mustard in abundance. It was just coming into flower, and providing ideal camouflage for roosting Orange Tips. I found just two, but as is so often the case, they shared the same flower head.
In view of the lowering light levels, I found taking pictures difficult, but tried flash - something I have never done before with any success. Here are the results, both with and without flash, and with slightly different angles and degrees of cropping. Very different results!
Here's to sunnier days without such complications.
