Dark Mayfly

This animal was found at Gordon Country in Southeast Queensland. It is not a Neuroptera, but a May Fly (Order Ephemeroptera). Mayflies are characterised by two or three long threadlike tails, called caudal filaments. I can't remember its size. I might move this species into a different gallery for Mayflies. Update 22/11/2016: Various Mayflies were found during the weekend. They were quite large in size, often didn't move, sticking to a plant or tree bark along a creek.
