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 is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).

Out on the lake today,saw some bass chasing the sawbellies.I know from past experience that it is almost impossible to get them to bite anything,but I had to try.Tossed a black wooly bugger into the fracas and pulled two nice browns out,one about 12" one about 14.I guess the bass werent letting them play

Next time you see that throw a streamer that is more of a realistic pattern. Personally I like to throw Clousers either gray over white or blue over white with lots of silver flash in the middle. I tie them on micro barb salt water hooks in #6 - #1/0. I catch lots of big trout on them. Big meaning 22" and more.
Doesnt matter what you throw,I've even used live sawbellies while spinning and cant get those bass to bite.Its pretty cool to watch,tho.I remember one morning watching with my son when he was about 8yrs old,there were about 20 very large bass coralling the baitfish into a screened corner of a tee shaped dock we have and as you saw the school of bait fish get really dense the bass would all leap thru the cloud and break the surface.Amazing watching them work together like that.
