White-legged Damselflies (Platycnemis pennipes) are dainty little predators that can be spotted on warm days fluttering along the vegetated margins of slow flowing rivers and pools. They can easily be distinguished from other Damselfly species by their pale appearance. Females are creamy in coloration, with pale eyes, while males are pale blue with striking blue eyes. The most impressive feature, however, is their broad, pale legs, from which their name derives. The males use these to display to the females during courtship.
The main flight period for White-legged Damselflies is from late May through to mid-August, depending on weather conditions. Eleanor Colver continues by saying “The BDS would like to encourage anyone who is planning on visiting their local wetland, on a warm day, to keep an eye out for this beautiful insect. If you regularly visit a wetland site, whether its bird watching or walking your dog, please sign up to survey the site as part of the White-legged Damselfly Investigation.”
