Paul D. Benedetti 1961 July 1 Sagehen Creek to Yuba Pass, Siemalo., Calif. Area #2) For lunch. Area is open, much sage brush + pine forest, lots of poplar along River. Collecting on mints along roads got a fril (coronis?) saw many Papilio's and a few sulfurs. Tony got a Pieris becheri. Got a \u2640 Satyrum californica on pussy paws, a Spylevia hydaspe on cone flower in a wet area, and in wet muddy seep got Nymphalis milbechi; Callophrys invider, saw some Phrygides. Saw a few robins, & a hairy wood pecker on poplars. After eating went North along the highway to find Tony. In a (white sp.) Ceanothus clappareli in the pines he got many hairstreaks (Satyrum behrii, californica, saepium \u2640), Callophrys nelsoni & invider, saw euphon, and also saw Papilos & a few frils. I got 2 behrii, saw a fritand a Green-tail towee. Went across the little Truchee River. Saw a satyr & I got a Spylevia (coronis), on the ceanothus got a \u2640 Callophrys euphon and in grass Cercoynis ochs. Tony got a lycacna heloider & a Spylezia serene. Saw a Mac Gillvary warbler in the willows here. Much of the area is good for Callo- phys nelsoni, with much firs & incense cedar mixed with the pines, though not many butterflies evident. Stopped at Yuba Pass (6700 ft.) or Calif. 89 to collect in emense meadow areas on both sides of the highway. Butterflies were common but few species: Plebius saepiolus, Colias, Spylevia serene & coronis, Papilio
