Paleacrita vernata by Rindge's keys
These photos are detailed enough to use with the keys in Rindge's Bistonini revision(1), leading to an ID of female Spring Cankerworm (Paleacrita vernata).

Some important points in the path through the keys:

The noticeably larger spines on the top of the second and third abdominal segments serve to narrow the genus to Paleacrita, and exclude Phigalia.

Then the high-contrast, black-and-white patterning on the tarsal segments leads to P. vernata, instead of the less-contrastingly patterned P. merriccata.
