Day 16 of the 2023 #dragonfly #AdventCalendar. Willow Emerald is a new species to the UK in the last 20 years. It's longer & thinner than the Common Emerald and flies later in the summer. This male at the wonderful #RSPB #Otmoor in September. They have spread across the UK quite rapidly, starting from Suffolk, now as far west as Oxford & as far north as the Humber #Oxfordshire #DragonflyAdventCalendar #wildlife #insects #wildlifephotography #invertebrates
