Last day of Red-veined Darter?

Heysham Obs
The first date for Red-veined Darter was a male photographed on 27th June (thanks Stan), not 'three weeks before' the previously assumed first.  A visit to Middleton at lunchtime saw cloud forming just before it reached the sun and it took a good half-hour to receive proper sunlight at which time the wind had increased.  So conditions not perfect

Middleton NR model boat pond lunchtime
Red-veined Darter - single male seen well and photographed by visitors.  Another male was seen over the water and was briefly "in cop" with (or holding) an ovipositing female which looked like Red-veined. 
Common Darter - 10+
Brown Hawker - 1
Emperor - 3
Black-tailed Skimmer - 7-9

Outfalls
Two adult Meds discerned through the heat haze

Butterflies
Single Comma, Red Admiral and Small Tortoiseshell on the office buddleia which has resurrected itself after a year off being cut to ground level to to anticipated works

Bordered Beauty and Six-striped Rustic new for the year and White-line Dart, White Satin, Slender Pug and Garden Carpet of note - the latter is scarce here
