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.

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 went fishing for a few hours yesterday and caught a few cool new bugs for the site. There's a little black caddis adult, a naturally crippled Isonychia bicolor spinner (check out the deformed wing -- it's cool), and a pretty Stenacron dun.

You can view them by going to the site homepage or the main "aquatic insects" section and looking at the "Recent Updates" list in the left column.
