Dragonflies: June 2015
The first Southern Hawker was seen along the Haven this morning.
The first Ruddy Darter of the year and another Scarce Chaser were in the Haven and a male Red-veined Darter was scudding about over Restharrow Scrape.
The improvement continued today with the first Brown Hawker of the year, in the Elms, a male Banded Demoiselle in Little Gully and another 2 Common Darters.
6 Black-tailed Skimmers were hawking over the scrape this afternoon – the first of the year.
After overnight rain cleared in mid morning some reluctant sunshine encouraged the appearance of the season’s first Common Darter, while all three chasers were recorded on the Estate.
A possible Red-veined Darter on Royal St.George’s footpath on the 17th was confirmed this afternoon when a male was seen at more or less the same spot.
Sunshine! Well, in the afternoon at least, encouraging the appearance of 4 Scarce Chasers along the Delf Stream.
The weekly treat to warm, humid conditions was rewarded by a (locally) astonishing count of 109 Banded Demoiselles on the public bit of the North Stream near the Observatory.
A warm, humid night encouraged a large emergence of Banded Demoiselles on the North Stream, with at least 45 males and 12 females between the start of the farm track and the small concrete bridge at the entrance to the blackthorn hedge that leads to the railway. This species has been increasing recently, but these are unprecedented numbers and at least 250 Blue-tailed Damselflies were present along the same stretch of the river.
After a fractious start to the month this morning was notable for five Red-eyed Damselflies and two male Banded Demoiselles along the North Stream.
3 emerging Emperors were doing their best to get going on the Estate this morning, with 21 exuviae close by indicating that decent numbers have already managed to do so.
