The Spinner thing... well, I'm not sure if S/spinner or D/dun is part of a scientific name as I thought you thought (
as did I!), or more part of a common name for a group! Very confusing names.
As for microscopy, I resolutely stand by that -
I deleted that by accident
I discovered my one and only
Mayfly in a shed on a wet, overcast day. It stayed for one photo but then fluttered off before I could get a better one.
