North Cave Wetlands – 15/06/2017

A partially cloudy morning, temperatures in the high teens with a moderate westerly breeze blowing. A good dragonfly day with the dragonfly ponds really coming to life. Highlight was a male Hairy Dragonfly Brachytron pratense briefly patrolling the margins of the eastern pond. Emperor Dragonfly Anax imperator showing well, difficult to ascertain how many males present, however at least one visited every one of the five ponds. I managed to find at least seven exuvia of this species on the eastern pond. A female was also present ovipositing in the new western pond. The latter pond with its bare margins is currently a great spot to obtain good views of Black-tailed Skimmer Orthetrum cancellatum, with several males present. Four-spotted Chaser Libellula quadrimaculata were on all of the ponds. Good numbers of Azure Damselfly Coenagrion puella, Common Blue Damselfly Enallagma cyathigerum and Blue-tailed Damselfly Ischnura elegans around the reserve.
