C.F.O. Hummer Skwala Stone fly
Skwala or Spring Stone
(One of the Yakima River WA Stoneflies)
The Skwala Stone emergence is the first important hatch of the season. Adults begin to appear during the last week or two of February and fish begin to key on them by the first or second week of March. The hatch lasts well into April and overlaps March Brown and BWO hatches. Skwala generally emerge at night, crawling onto rocks close to the shore. Mating often occurs as soon as the female frees herself from the nymphal shuck.
Note: Aslo makes a good carpenter ant pattern.
