Synonyms and other taxonomic changes
Acidalia ? sparsaria Walker, 1862.
Boarmia psilogrammaria Zeller, 1872. Later synonymized under A. sparsaria by Hulst (1895, p. 42).
Identification

Larvae are twig mimics with numerous annulations per segment, more reminiscent of Sterrhinae species. The prothorax features a pair of dorsal thorn-like projections that bring to mind Geometrinae species. Noticeable dorsal warts on A1 - A5 and A9, closer set on A9. Crochets arranged in pairs. Setae very short. Coloration variable but head capsule appears to always be darker than ground color. Head capsule itself is comprised of two angulate lobes.
Food
Larvae recorded feeding on Woolly Buckthorn (Sideroxylon lanuginosum) in East Texas.
Remarks
Zeller (1872) described the new Geometrid "Boarmia psilogrammaria" which was later synonymized with what is now Pimaphera sparsaria. B. psilogrammaria was described from Texas, thus extending the known range of P. sparsaria from Florida to Texas. More recent information suggests that Texas and Oklahoma are the epicenter of the distribution of the species with very few records elsewhere (Missouri, Louisiana, Alabama).
See Also
Pimaphera percata, which as currently understood is confined to Arizona.
