Driving up thru Somerset county this morning and pulled off a couple times along the Yough, Laurel Hill and Lower Casselman. It was bright and warming and I saw good showings of what Hoover id'd for me years ago as Hydrophyche (sp??), i.e. Spotted Sedges, on all 3 rivers.
These are pale tan, hay-like in color, not the yellowish Straw-like color we sometimes read about. Size 16 and 18, pale tan wing and body, speckles on legs, not the larger, bulkier overall black-ish body of a true Grannom.
It's a morning hatch here and usually preceeds the green caddis, (Rhyacophlia ??) that gives us really great fishing in May.
