Female Pictetiella expansa Stonefly AdultFemale Pictetiella expansa  Stonefly Adult View 12 PicturesBased on photos, this specimen seems to key out (using Merritt & Cummins 4th Edition) to Pictetiella expansa, but some of the characteristics aren't 100 % clear. However, that species is listed as occurring near Puget Sound and the head markings are similar to (albeit not a perfect match for) those of a male from Colorado in the scientific literature here: https://www.researchgate.net/figure/Head-and-pronotum (Pronotum: The top of the insect prothorax.)-dorsal (Dorsal: Top.)-Pictetiella-expansa-Boulder-Co-Colorado-North-Fork-Middle_fig1_315373449
