This rather spindly wild carrot was growing in a sunny south-facing clearing amongst the willows, alders and dragonfly ponds at RSPB Old Moor nature reserve.
I was drawing the fly which settled on my left arm when a fresh-looking comma settled on my right leg. The fly then moved to my nose and, as it had a suspiciuosly long beak-like proboscis, I had to brush it away, losing my chance to sketch the butterfly.
