A little quiz for you. See how you go with these...and you'll be doing me a favour as there's one I'm not 100% sure about myself!

Not sure about the rest but the bottom one looks like a stone fly to me Mat.

I thought you were going to say they were all Grouse-sedges Stuart.

Quick quiz! The top one looks brook dunnish, they're still emerging on the Rhondda so no doubt there'll be a few hatching op north.

Nice pic of the stonefly cases, I haven't seen any of that in the Taff or Teifi systems but the Wye at Hay gets phenomenal stonefly hatches and the margins can be littered with thousands of those shells on occasion.

Sedge and stonefly ID seems to evade me, no idea what those sedges are - plenty of 'em though - but the stonefly does look willowy to me.

Yes the stonefly cases had me stumped for a while! The culprits are I reckon, of the leuctra species, but I'm no stonefly expert (or any expert for that matter!).

The upwing is, I'm almost certain e. dispar the autumn dun and the caddis, well they look very much like r. dorsalis to me although if you look closely there do seem to be more than one species there.....

Must try to take a close look at the bogus Brook Duns, I hadn't thoughtthey may have been Autumn Duns - up to now - obvious really! Well spotted NCA

I only recognised the stone fly, thought the up wing was a May fly, and the caddis - cinnamon sedge.

But here's a suggestion for you; well three of you actually - Matt (NCA) Colin (Diawl Bach) and Chris ( Whinging Pom) I think you three guys could run an "Entomology Information Thread" With the knowledge you have between you, I'm sure we would all benefit from such a thread!! There's been no one since TC left the forum, to take up the mantle of schooling the rest of us to the recognition of fly life and insects! I'd read all you publish; as I'm useless at recognising the fly life and aquatic insects!

I know it would take a good deal of your leisure time - that's why I suggested a shared tutelage!

Just a suggestion!

The big ecdyonurid is an August Dun female, can't see any claspers, also known as Autumn Dun. The old lady transforms into a Great Red Spinner, one of Dr Malcolm Greenhalgh's favourite spinners. flight period is August--September. The heavy veination of the wings is a good clue to identity of this ecdyonurid, along with the mottling. The other heavily- veined wing fearture is seen in False March Brown, which also has mottled wings; while the remaining two ecdyonurids, Large Brook Dun and Large Green Dun, have barring patterns on the forewings. Not quite as distinctive as March Brown Dun wings,which is why I can't understand why False March Brown is so-called. Jada.
The stonefly, if a little larger than the needles, is most likely Willow Fly.
