The White-legged Damselfly, also known as Blue Featherleg, has distinctive broad, creamy-white legs with long hairs on the tibia giving a feathery appearance. Other characteristic features of this damselfly are the pale orange pterostigma – the coloured cells found towards the tips of each wing, and a combination of a broad black ante-humeral stripe on the top of the thorax and two finer stripes on the side of the thorax that join towards the head.
White-legged Damselflies are found locally along slow flowing muddy-bottomed rivers across southern England and often in association with Banded Demoiselles who share a preference for this habitat. Their flight season is typically between May and August.
Pre-mating courtship rituals are reported to be complex in this species. Females will use a bouncy, jerking flight to first attract males, who then will show their white legs in a fluttering display flight in front of females prior to mating.
