On the window of an isolated building. A 2-tailed mayfly, possibly Siphlonurus. Looking at an adjusted version of the photo shows yellow and dark (black or brown) stripes on each abdominal section. The dark stripe widens on the side to give a triangular appearance. Can anyone give a species ID, please?
