Beautiful Demoiselles and a Crescent Plume

Beautiful Demoiselle ♂, Calopteryx virgo
On Friday 15th July I did my Mill Hill butterfly transect: first Chalkhill Blue of the season, Comma, Gatekeeper 18, Green-veined White 2, Marbled White 11, Small White 1, unidentified Whites 9, Meadow Brown 14, Peacock, Red Admiral 11, Small Tortoiseshell, Six-spot Burnet, Light Brown Apple Moth. 
 Outside the Cement Works on the A283 I found an Essex Skipper, a Six-spot Burnet and a Crescent Plume. 
  At Woods Mill I watched a male Common Darter, a female Blue-tailed Damselfly and 5 Beautiful Demoiselles (4 males, 1 female). Two of the males displayed vigorously at each other. I also found my first Golden Argent, a small 10mm moth that kept returning to the tip of a leaf and flashing its wings open, presumably to attract a mate. There were caddis and mayflies on the reeds.
  On Saturday I visited the path by Littlehampton golf course again hoping to see White-letter Hairstreaks on the brambles. I think I saw a couple but couldn’t be sure as they flew fast and disappeared. There were Red Admirals everywhere, including a trio in a dogfight, plus Commas, Large Whites, Large Skippers and Gatekeepers and a Yellow Shell.

  Later I visited Woods Mill and photographed Beautiful Demoiselles again, including a mating pair. Two males in adjacent territories kept meeting and displaying, sometimes gentle fluttering and sometimes dogfighting. I spotted a late instar Peacock larva racing across a patch of Fool’s Water Cress by the river.
