One of the best things about writing this blog is that I’m constantly learning new things. When this gorgeous creature flitted across my path in Bute Park on Wednesday, I thought ‘Ooooo, my first dragonfly of the year!’ Wrong! This is a damselfly, a female of the very aptly named species Beautiful Demoiselle (Calopteryx Virgo).

So, I asked myself, ‘how do I tell the difference between a dragonfly and a damselfly?’ It seems there are four basic differences that even I should be able to spot:
1) Body shape: dragonflies are bulkier, shorter and thicker, whereas damselflies are slender and delicate.
2) Eyes: a dragonfly’s eyes are much larger, wrapping around from the side to the front of the head, often touching. The eyes of the damselfly are also big, but tend to be more to the side of the head, with a definite gap between.

3) Wing shape: the hind wings of the dragonfly are larger than the fore wings and broaden at the base, but the damselfly’s wings are both the same size and shape, and narrow markedly where they connect to the body.
4) Wing position: when resting, the dragonfly always spreads its wings, whereas the damselfly rests with its wings together above its body.

Above is a photo of a female Brown Hawker dragonfly (Aeshna grandis), taken last year, so you can see the differences. And, hopefully, my rather early Beautiful Demoiselle will just be the first of many of these heavenly creatures.
It can sometimes be difficult to tell particularly when there are both of a similar size in the vicinity. We have both damsel flies and dragonfiies in our garden that visit our pond. But to my eye, the dragonflies are actually very long. They are both types very beautiful insects. We’ve some iridescent blue damselflies that are gorgeous, and the big green dragonflies, too.

I envy you your pond, Val. I’m sure it brings you many natural treasures. 🙂

It does indeed. Unfortunately a couple of treasures it brought a few years ago were a heron and an otter, both of which tucked into our Koi of which we now have none. But that’s been good for the frogs and others. 🙂

Hmmm, herons are very opportunistic that way but an otter … how amazing! And frogs are good! 🙂
