so much testoterone but not enough females, yet

An enlighted landowner manages his big wood in Bucks for iris. It is  wall to wall Sallow along the rides. I only had one hour on saturday morning, from 10 until 11. Once before, two years ago, I had a similar experience: 31 sightings, at least 20 individuals, all males. The extraordinary thing was that they were all behaving identically: very rapid flights in and around the Sallows, keeping very close to the vegetation, sometimes in the Ashes behind; no landing whatsoever. Because there were so many, inevitably they clashed, but not for long, because they needed to get back to looking for the ladies tout de suite.
