Red-veined Darter

I received a note that a record had been posted on Twitter by Jacob Spinks of  an immature make Red-veined Darter at Pitsford Reservoir. The location was a shallow pool in a bund area from the main reservoir. The photo doesn't show a teneral, but the male was yellow so definitely immature. This is suggestive that breeding occurred earlier this year during the major influx of this species. No others have been seen. Red-veined Darters can crop up anywhere, and this is an out-of-the-way site so its not surprising that adults weren't seen here in June.

At Ditchford and Summer Leys plenty of Migrant Hawkers are buzzing around the main lake alongside Common Darters, Red-eyed Damselflies and Common Blue Damselflies.

At Finedon, Willow Emeralds are still around, but still in low numbers. I succeeded in finding fresh egg-laying scars in the central willow tree, about 3-3.5m up.

On sunday 17 Sept, James Underwood reports seeing Banded Demoiselle on a stream at Weldon. This is an unusually late date for Demoiselles.
