Blue-winged Olives

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.

Male Psychoglypha (Snow Sedge) Caddisfly Adult Pictures

This Psychoglypha adult was found clinging to my garage door in the evening on April 9, 2013. It measures 21 mm in length, from the front of head to the end of wings. It is my hope that Creno will be able to identify it to species based on the image of its genitalia. However, if other images are required for a species ID, the specimen is available, so they can be easily taken. Thanks, Roger Rohrbeck, Mercer Island, WA.

This caddisfly was collected from Spring Brook in Washington on April 9th, 2013 and added to Troutnut.com by Taxon on April 12th, 2013.

I cannot determine most species in this genus without clearing the parts and looking closely. Sorry.
