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.

Damselfly Nymph on the Prowl

Damselfly nymphs are among the most effective invertebrate predators in freshwater. You have to see one in motion to get a feel for their slow, deliberate style of stalking.

Slim and Sparse

I have diddled and fiddled to produce decent damsel nymphs for some time now and it is tough to come with up something good either impressionistic or realistic. The one thought, when I watch them move in their environment,is always that they are very sparse predators. So whatever I tie, and it always seems to be an improvement over previous productions, is something slim. Good thing fish often are not too fussy.

Calopteryx
These are beautiful as adults. Wherever you get these, you should go back when they are emerging. Alternatively, keep them in your aquarium until they emerge. They're easy enough to keep...except when you have Aeshna with them...
