Males go into 'find the lady mode' in mid-Bucks
Up until today, I had only observed male territorial behaviour this season: i.e., sticking to the same clump of trees, fighting with other males, perching and gliding around these trees. Today, the behaviour was completely different. I saw four males in different parts of a wood, flying rapidly [i.e., no gliding] in and out of the tops and sides of trees, including big Sallows, tracking along the rides, and never landing: what Matthew calls 'Oak edging', but, of course, all trees are being searched for females. My first sighting was of a female, flying around and in and out of Sallows, landing briefly, but I don't think she was ovipositing.
