smallieFanatic 0 Report post Posted September 9, 2009 Here are two nymphs I found, can you guys ID them for me. I know that the top ones a stone and the bottoms a mayfly--but thats it. Thanks in advance. Jan Quote Share this post Link to post Share on other sites
the saltydog 0 Report post Posted September 9, 2009 Jan - The top one is a Heptageniidae Stream Mayfly, I think that bottom one is an immature Perlidae common stonefly nymph Great pics of both! -Greg Quote Share this post Link to post Share on other sites
smallieFanatic 0 Report post Posted September 9, 2009 Thanks for the ID Greg, the stonefly I did think it was a bit small--I could see the empty husks of big honking stones all over, easily four times the size of this one. Jan Quote Share this post Link to post Share on other sites
Futzer 0 Report post Posted September 9, 2009 Hi Jan and Salty, Top I am calling juvenille golden stone, cause I believe you were in Idaho for these and the Heptageniidae are not common there. Cheers, Jeff. Quote Share this post Link to post Share on other sites
smallieFanatic 0 Report post Posted September 9, 2009 I have a seen a few Golden Stones around there, maybe I should find a decent Golden stone pattern? Thanks for the help! Jan Quote Share this post Link to post Share on other sites
TitanFlies 0 Report post Posted September 9, 2009 As far as my entemology goes, based on the head and segmentation on the top photo, I'm gunna call it... wait for it... a stonefly and not a mayfly. Second one I know for a fact not to be a stone. I would say a Deleatidium... could be completely wrong... which is 90% of the time. Quote Share this post Link to post Share on other sites
smallieFanatic 0 Report post Posted September 9, 2009 I know the top one is a Stone, its the exact type I was unsure of. Quote Share this post Link to post Share on other sites
the saltydog 0 Report post Posted September 9, 2009 The coloring threw me off, I'm looking at the Audubon field guide which doesn't have a pic of a golden stone. But re-looking at the head I can see the resemblance better to the stone. Also the 2 tails rather then 3 should have been more of a clue. Quote Share this post Link to post Share on other sites
Taxon 0 Report post Posted September 9, 2009 Jan- Your 2nd photo is a Mayfly of family Ephemerellidae, genus Drunella, either D. flavilinea or D. coloradensis, which are difficult to distinguish for one another in their nymphal lifestage. Western fly fishers generally refer to them as Flavs or Lesser Green Drakes. Quote Share this post Link to post Share on other sites

Futzer 0 Report post Posted September 10, 2009 Hi Jan, wish I had a size reference, I am thinking 14. I'd throw a grey drake at it. Cheers, Jeff. Quote Share this post Link to post Share on other sites
smallieFanatic 0 Report post Posted September 10, 2009 It was a small one, perhaps a #18. Grey drake? I'll have to google that one. Thanks for the help! Jan Quote Share this post Link to post Share on other sites
Futzer 0 Report post Posted September 10, 2009 Drake is too small for an 18, and without going all latin on you. I find bugs at the river I am working and tie to match it. Streamside inventions have worked well for me. And yes Jan, I do not know many of the Latin names, though I do respect anyone who does. I think I can out fish them though, nothing in nature is preprogrammed. Cheers, Jeff. Quote Share this post Link to post Share on other sites
