The Half-wing Moth
6658 -- Phigalia titea. One of the very early season Phigalias. You might also encounter Phigalia denticulata (Toothed Phigalia 6659) and Phigalia strigateria (Small Phigalia 6660) which have different patterns of the three major lines running across the wings. See 6659-6660 and 6658.

Hmmmm...
Hey Bob,

I checked through my copy of "Peterson's Field Guide to Eastern Moths" (1), and it looks closer to Phigalia strigateria (see pl. 52, fig 20). Covell also indicates that the bands don't touch on P. titea...which they seem to be doing here. whaddya think?

Could be, maybe....
Tony, sorry I didn't see this earlier. Covell states that the lines don't usually touch. I based my opinion on the shapes of the median and pm. lines. After agonizing over this again (it is not really clear cut) I still prefer the Half-wing, but I could be wrong.
