We went on a wonderful walk on the North Norfolk coast this morning, and everywhere we went came on bushes of luscious blackberries. Accordingly, progress was slow at times.

And everywhere we went we were accompanied by dragonflies, often flying in pairs in very tight formation. Here’s one who alighted on my sleeve when I was trying to photograph the berries.

LATER: Richard Earney emails to say that this is “a mature Common Darter” (aka Sympetrum striolatum). What a wonderful thing it is to have erudite readers.
