Dragonfly Discovery There are thirty species of dragonfly to be found in the UK, but habitat destruction and the effects of climate change are threatening their survival. Changes in land use mean there are now fewer ponds. These ponds were good habitat for dragonflies, making the garden pond an extremely important place for them. Through submitting a sighting, you can build up a picture of which dragonfly species use gardens, at what times of the year and in what numbers. Where and when did you last see a dragonfly?
