I was surprised too, especially as I had just spent about 20 minutes sheltering under a tree during a particularly heavy downpour. I forgot to add there was a dragonfly on the iris in the corner that looked as though it had just emerged from the water. It's shape suggested it was a chaser, but my knowledge of dragonflies doesn't extend beyond the sheets of paper you gave us at the meeting, so I have absolutely no idea what it was.
