Dragonflies and Damselflies
Dragonflies are usually much larger and stockier than damselflies and have their wings spread out when resting whereas a damselfly is mostly much smaller and usually has it's wings folded back when resting.
I love the large hawker dragonflies. Mostly I just see them zooming past along the river or. if at a pond. flying round and round the edge. For that reason I find it very difficult to get a photo of one. However very occasionally I spot one sitting still.
The smaller dragonflies can be spotted sitting still more often and so are easier to get a photo of.
I love the electric blue of the damselflies, you can get various different types on this walk including red but the blue ones are the most common to see.
