Blue-winged Olives
Baetis
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).
Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and
fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or
support the project for an enhanced experience here.

I'm a very sporadic visitor to this site, but I often send anglers new to entomology here. And IMO one of the best things here are the photos.
That being said, our club forum here in the DC area had this question posted:
Why don't fish eat water striders?
Secondarily, my experience with water striders on moving water, such as the Potomac, is that if water striders are present, fish will NOT be present. Or is this an old wives tale?

Namfos,
The reason water striders are not eaten is because of a scent gland on their thorax which evidently gives off a smell which is unappreciated by fish in general.
I've seen trout swimming below water striders. Not too commonly, but it happens.
