Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.

You are asking for an awful lot of data and information for a first time poster. I'd suggect you Google "Flies needed for spring steelhead". Then when you get a few anwsers copy down the names of those flies and Google "fly pattern recipe for XXXXX" You fill in the name of the fly. I'd recommend Hares Ear, Prince, Pheasant Tail, Black stone fly al in sizes #12 - #16. Have fun.
