I guess Red-bordered Emerald - Hodges#7033 (Nemoria lixaria)

I vote for lixaria because yo
Initially I thought lixaria, but I actually think yours is bistriaria. -Nina


From the Bugguide page on Species Nemoria lixaria - Red-bordered Emerald - Hodges#7033

"Identification
Adult: wings pale green with jagged white AM and PM lines and red terminal lines; tiny black discal dots on all wings; fring checkered red and white; abdominal spots white ringed with red; melanic specimens brownish-green with dark brown lines and fringe"

Red-fringed Emerald - Hodges#7046 (Nemoria bistriaria)
Adult: wings in summer form green with white AM and PM lines, red terminal line (sometimes lacking), and checkered pink fringe; AM and PM lines vary in strength and clarity among individuals (AM line very faint in some specimens); black discal dots on wings may or may not be present; small white band on front of reddish foretibia; abdomen green with several cream-colored spots rimmed in red
spring form usually light brown except in far north (from approximately Pennsylvania to southern Quebec and Ontario, representing subspecies N. b. siccifolia) where the spring form is green

 
I'm back to lixaria
after looking on the moth photographer group's site with living photos and pinned plates, I'm back to thinking lixaria mostly because of the very prominent black discal spots, and the abdominal spots clearly ringed (not just rimmed) in red.

hopefully a seasoned lep-person will chime in and give us a definitive ID... Nina

 
I agree
I think Nemoria lixaria is a better match.

I think it's the red-fringed emerald
if I read the info pages correctly, one clue seems to be how wiggly the white postmedian lines are - much more jagged on the red-bordered emerald (below):



I'm absolutely not an expert, though, and I see stronger red markings on the edges (which yours has) are supposed to indicate red-bordered emerald, so I can see why you're confused - I am, too!

 
Added another image
I added another image (different specimen) taken 4 days later to see if it helps. I figured it might be the brown version of Red-fringed Emerald. Being in a state with overlapping species is hard. I had the same problem with a Pine Sphinx caterpillar a couple of days ago.
