I am pleased it was possible to identify it from this picture.
Hello Martinjohn, Ive just read the title of your original posting. Have I missed that and posted an ID before properly awake!?
If so really sorry.
Based on your identification! Thanks.
Thanks for response, I was just about to edit my above message and I think I will. Someone could very well disagree with this ID, someone with more experience than I on ephemeroptera!
You have amazing confidence in me!!!!!
I hope I havent mislead, but on studying good illustrations I think the suggested species is a fair shot.
Just noticed I cant edit above, what I wanted to change was-- "posted a -possible- ID before fully awake".
I think the idea of iSpot is to teach people how to identify organisms. Your original identification gave "Confidence: It's likely to be this, but I can't be certain." which seems reasonable. There is a very good photograph at http://www.flyforums.co.uk/entomology/57605-ecdyonurus-torrentis.html which looks a lot like my specimen. If an expert says no, then we will learn something. Anyway, it is not always possible to have a full identification from photographs alone.
It is true that it is not always possible edit some things one would like to alter; have to double check before pressing the button. It has happened to most, I believe, certainly to me. Thanks again.
Yeah an expert could very well say its just not possible to give a concrete ID from the photo alone. I used a very recent and comprehensive (atleast it seems to be) field guide book to make my 'possible ID'.
Its a lovely little book and I believe it to be useful and from a reputable author, is it ok to recommend and name books on iSpot?
Yes, I am sure it would be most welcome to give details of the field guide.
Ok, I think its a superb book, not a specialist book but a very educational general book on freshwater life.
'Freshwater Life, Britain and Northern Europe' by Malcolm Greenhalgh and Denys Ovenden. 2007.
Its a 'Collins pocket guide'. Most enjoyable.
Thanks for the recommendation!
I cant recommend it enough, really nice little book. I hope you enjoy it also.
Just a note on the common name used here. Ephemerid is an old name for the Ephemeroptera, now generally applied to just the Ephemeridae family (true mayflies). This is what I would call a large brook dun, but there are many anglers names for species of Ephemeroptera (indeed the whole order is variously known as mayflies, up-wing flies, dayflies, etc.)
Thanks for this info Inopinatus, I used the term with a very slight anxiety that it wasnt properly or sufficiently scientific, and yes you are right, the term ephemerid is a term which would be used mainly by anglers.
The English name 'Large Brook Dun' does indeed seem to be used by many people, in preference to brook dun as I have used, the reason for this was simply due to its being used in the reference book I mentioned above.
I think Ive got it?
I'm afraid I've only just noticed that this record is from Italy! I have no clue about species from outside the UK, other than that this is definitely a mayfly!
