Surveyors working with London Wildlife Trust’s Water for Wildlife project spotted a pair of willow emerald damselflies whilst looking for dragonflies and damselflies in Clissold Park, Hackney, in late September. By tracking such insects the project is mapping out the health of London’s freshwater ecosystems.
Research volunteer Sonja Todd spotted the male and female willow emerald damselfly in reeds growing in the New River in the park.
