At last

28th May 2012, Monday

There has been a big emergence of Hairy Dragonfly and Four-spotted Chaser at Castle Water in the ditch north of the hide, today I collected 64 Hairy Dragonfly and 86 Four-spotted Chaser exuviae. Teneral adults were easily found in the long grass nearby and it was a real pleasure to see so many dragonflies take to the air. Sadly there has to be some losers. I found several of each species that had failed to complete full wing expansion and strangely a Four-spotted Chaser larva that had completely failed to start the emergence process.
