Hi Irwin and Erland,
Thanks for your comments.
Judging by the very soft shadow beneath the female I suspect the day was slightly overcast - otherwise no special technique employed.
Erland, thank you for the tip on Donaciinae (reed beetles). I quickly confirmed that you were absolutely on the right track but it still took me a while to narrow the species id down to a particularly colourful
Donacia vulgaris or (Donacia simplex). These two species look so similar- could it be possible that one or other may be a earlier pseudonym?
By the way I really enjoyed
your website on Danish dragonflies. Some great photos and some VERY interesting information -
highly recommend anyone interested in the odonata pay it a visit.
