Taxonomic Note
The was described by George D. Hulst in 1886. The Eusarca is part of the diverse geometrid Ennominae, which contains many species with conservative external that complicates field identification.
Data Limitations
This has only 41 observations on iNaturalist as of the source date, indicating it is either genuinely uncommon, underreported, or difficult to identify from photographs. Published biological information appears sparse.
