Closeup insects by Bnewell from the Touchet River in Washington

Male Acentrella turbida (Tiny Blue-Winged Olive) Mayfly SpinnerMale 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.

Hydropsychidae Caddisfly AdultHydropsychidae Caddisfly Adult View 2 PicturesThese specimens are either Cheumatopsyche or Hydropsyche. They escaped before I could catch them.I suspect, based on size, they are Hydropsyche, they are about 1/4 inch in length. Both H. occidentalis and H. californica are common in the Touchet River.
