On warm, still summer days, Mayflies and Alderflies may be seen along the riverbank. Adult Mayflies are generally short-lived as they are unable to feed, and may only survive for a matter of days, dying soon after mating. They are often seen in the late afternoon, swarming above the water’s surface.
The adult Alderfly tends to be rather lethargic and is often seen sitting on waterside plants, such as Willow and Alder. They have four large dark coloured wings, which are folded back along the body when the insect is at rest.

What better resting place than on a nettle leaf for the Alderfly!!
