When I got home from work the mayfly was on the inside of my kitchen window. I had the window open for a while yesterday, so presumably it came in then. Mayflies typically require high quality water bodies with plenty of oxygen and little pollution - I have never seen one in Endon before. I doubt the canal would provide suitable habitat and I suspect the local streams to be fairly eutrophic (nutrient-rich) therefore low in oxygen judging by the quantity of filamentous algae and other similar members of the sewage fungus community that blankets the stones it the bottom.
The stream/ditch by Station Road, Endon.
Two-tailed Mayfly in my house today.
