This specimen is the best match I could find for the description below. It has been collected in N.S. and its best known host plant Solidago flexicaulisis found in my area.
Adult Markings: The following description is based in part on that of Kellicott (1878). The head is white. The thorax is also white, but often has faint brown streaking or spotting. The labial palp is mostly white with brown scales on the outside of the second joint. The terminal joint is white, with a black subterminal band and a tiny white tip. The antenna is white with thin, brown annulations. The forewing ground is white, and is overlain with black spots and larger reddish brown to dark brown dusting and marks. A large reddish brown to dark brown hemispheric patch begins along the costa at about one-third the wing length and extends rearward to one-half or more. The patch extends inward towards the inner margin to about two-thirds the wing depth. The anterior margin is oblique and relatively clean-cut, while the posterior region tends to be irregular and spreads posteriorly to varying degrees where there are often one or two smaller reddish-brown to dark brown patches. The inner margin usually has two blackish dashes or spots, one near the wing base and one just beyond one-half. The apical third is whitish, with varying levels are dark brown mottling. The basal third is also white, and often with a reddish brown diffuse costal patch, along with a small black patch at the base of the inner margin. The cilia are dull white with darker speckling. The hindwing is gray and the cilia lighter. The abdomen is gray and the first three segments are yellow above. The legs are blackish with narrow, white annulations. (Moths of North Carolina - 2024)

Inflorescence mostly secund like S. uliginosa but with sparsely puberulent stem and weakly clasping petiole bases. Growing with both species intermixed on a gradient between boggy lake edge and more upland old trail clearing

On goldenrod. Pulled off inside petals/leaves, which were red tipped. Inside progressively thinner and more transparent red tipped leaves, I found hollow grass seed like center. Slight darker green coloration at lower end and mark on side like maybe something already exited. inside the capsule two thin threads with growth tips on one end - flower parts? No cavities below the hollow grass seed like center.

My personal hell.
I can't figure out this Violet.

Lateral petals bearded.
Spurred petal glabrous.
Calex eciliolate.
Auricles short and round.
Leaves twice as long as wide, minutely pubescent adaxially.
Leaves glaberous abaxially.
Petioles of early leaves glaberous.
Petioles of new leaves pubescent.
Rhizome short and thick.
Non-stoloniferous.
