The Hottest Weekend!

Well, what a change in temperature. Two weeks ago, temperatures were hovering around the 10-12 degree mark with a chilly north-westerly wind. This weekend has seen conditions approaching 30 degrees. Dragonflies like the hot sunshine, however at temps over 30degrees, they become less active.

On my way home from a business trip on Friday 21 May, I took a detour to the Nene at Lilford, Waddenhoe and Aldwincle looking for Scarce Chaser. This time last year, emergence was well underway, but this year I struggled and only found one. The cold weather must have delayed them somewhat. I expect now that emergence has begun, we will start to see them now and the Bank Holiday weekend may be a good time to look.

At Yardley Chase, Downy Emeralds were emerging in good numbers (see photos above) and Large Reds were very active mating and oviposting.

The River Nene at Thrapston yielded another Scarce Chaser along with ~100 Banded Demoiselle, 2 Hairys and many Common Blue and Red-eyed Damselflies.
