Underwater photos from the Touchet River

This is a tailed frog, genus Ascaphus that lives in cold fast streams of the west. Perhaps this critter is one reason that leech flies work in some trout streams.

Closeup insects from the Touchet River
Male Acentrella turbida (Tiny Blue-Winged Olive) Mayfly Spinner
View 3 PicturesI would not like to have to match this hatch. These are the smallest mayflies I have ever seen. I used to think Caenis was the smallest adult mayfly in the west but these guys are about 4mm long. The male eyes are two toned, brown above and olive below. The abdomen is dark brown interspersed with light brown. The abdomen is clear for the anterior (Anterior: Toward the front of an organism's body. The phrase "anterior to" means "in front of.") 2/3rd and the remainder is white. The tails are twice as long as the insect. There is only one pair of wings. Female Claassenia sabulosa (Golden Stone) Stonefly Adult
View 3 PicturesI think this is one of the most poorly understood of the golden stoneflies. It is rare to see any articles about it or fishing the hatch. It emerges late in summer usually on medium to large rivers.The adults are quite secretive but it is something to see the adults run across the water surface. These guys can really run. The males have short wings.The females are up to 1 1/4 inch long rivaling the salmonfly as the largest adult stonefly in the west.The adults are not real golden in color, especially the females which are more of an off yellow to off white abdomen. In handling the adults it is obvious that they shun direct sunlight. I find them by turning over rocks close to the water's edge.
