|Note the obvious 'spur' marking on the thorax. A key feature of this species|
|You can just about make out the pale wing spots, or pterostigma, another key feature|
A damselfly with very few 20th century records in the U.K., but first seen in regular numbers in Suffolk in 2009. This species has been steadily moving eastwards over the past few years and has now been sighted in the Peterborough area on at least two occasions, one of which being the sighting that I had at Kings Dyke nature reserve a few weeks ago.
Not being a dragonfly or damselfly expert, I quite happily took the above photos without realising the importance of the sighting, or what species I was actually photographing. I knew it was an emerald type damselfly because of the colour of the individual, but it wasn't until I looked at the photos in greater detail and cross referencing with my dragonfly field guide, that I realised the individual was a Willow Emerald Damselfly (I think a female). A new species for the reserve and only the second in the Peterborough area, with the first being a week previous to mine.
