Damselflies and Dragonflies in 2011
The appearance of this year's first (for me) Black-tailed Skimmer on July 11th prompted me to write an article half-way through the year about the damselflies and dragonflies of the area 'til now.
My first record of the year (or at least, the first photograph) is of the Blue-tailed Damselfly Ischnura elegans, in Wanstead Park on 23rd April. The next species was the Large Red Damselfly Phyrrosoma nymphula by Heronry Pond on 25th April. Of note is that this species is often the first to be observed of the year, and often in my garden.
Next came the Azure Damselfly Coenagrion puella, which appeared in my garden on 4th May and by this time there were many Large Reds in the Park, plus the Broad-bodied Chaser dragonfly, Libellula depressa. On the 9th May, the Large Reds were busy mating and egg-laying in my garden pond - an annual occurrence. It was on this day that I was honoured to watch a larva of that species emerge from the pond, and watched it right through the process until it flew off. A video is available here.
The next damselfly species was the Small Red-eyed Damselfly Erythromma viridulum, on the Ornamental Waters in Wanstead Park on 10th May. These were conveniently perched - as they often are - on lily-leaves. The second dragonfly species appeared by Heronry Pond on the 16th May - the dramatic Black-tailed Skimmer Orthetrum cancellatum, in this case a female. Azure Damselflies were egg-laying on 16th May on the Heronry Pond, and by the 20th there were many Azure as well as Common Blue Damselflies, Enallagma cyathigerum.
A young Black-tailed Skimmer was hawking over the brambles at the base of "Bullet Hill, opposite Aldersbrook School, on 30th May, and there was a nice golden female in my garden on 2nd June. Also on 2nd June the lovely Banded Demoiselle damselfly Calopteryx splendens was seen by the Roding. In the garden on 21st June were Azure and Common Blue damselflies.
On 10th July a Banded Demoiselle was seen in Aldersbrook Exchange Lands, and on 11th July a male Black-tailed Skimmer was basking in the sunshine on the banks of Alexandra Lake on Wanstead Flats whilst two Emperor dragonflies Anax imperator were hawking over. There was also a male Emperor at the top of the Glade in Wanstead Park, and Red-eyed Damselflies Erythromma najus lily-bathing on the Ornamental Water. There were also some brown-bodied dragonflies which may have been Brown Hawkers, but I'm not sure.
So there it is with the dragonflies and damselflies up until now. That makes 10 certain. The list is as follows - in order of appearance!:
Blue-tailed Damselfly Ishnura elegans
Large Red Damselfly Pyrrhosoma nymphula
Azure Damselfly Coenagrion puella
Broad-bodied Chaser Libellula depressa
Small Red-eyed Damselfly Erythromma viridulum
Black-tailed Skimmer Orthetrum cancellatum
Banded Demoiselle Calpoteryx splendens
Common Blue Damselfly Enallagma cyathigerum
Emperor Dragonfly Anax imperator
Red-eyed Damselfly Erythromma najas
