The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

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?

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.
