[obol] Butterfly, or moth Help

[bigfishy at att.net]

     We went hiking in the Umpqua national forest, specifically the Brice/ Trestle Creek Trails (DeLorme pg 42) and my wife had a black butterfly land on her leg.  The butterfly had all black wings with a couple orangish dots above a white arrow shape that pointed towards its body on the underwing.  Anybody have any idea what it may be, or point us to a website that could help us identify it?
