On a windy day, I came across my first emerging Brown Hawker at Ditchford. One emergee had damaged wings and another emerged right into a spider's nest and was sucked dry by the time I found it. Also several Black-tailed Skimmer (always good to see here as they are declining somewhat), Hairys and the usual Damselflies.
Mark Piper and Nick Roberts report seeing a Scarce Chaser on the River Nene at Harpole Mill. This is the furthest west on the Nene that Scarce Chaser have been recorded. There was a sighting 2.5km east of here last year, so I am left wondering if there may be a small colony nearby. It's certainly a fair way to fly from the usual sites near Thrapston.
