Probole is a Nearctic of geometer moths (Geometridae) distributed across Canada and the northern and eastern United States. Taxonomic revision in 2007, incorporating morphological, mitochondrial , and developmental evidence, concluded that the genus is , with all variation attributed to a single , Probole amicaria. Previously recognized species such as Probole alienaria and P. nepiasaria are now treated as intraspecific variants. The species exhibits substantial variability including , geographic variation, and seasonal dimorphism in .

Identification
show seasonal dimorphism, with spring and summer forms differing in appearance. The was historically confused due to extensive intraspecific variation in wing pattern and coloration. Accurate identification now relies on recognizing that all Probole specimens represent variable forms of P. amicaria rather than distinct .

- Other Geometridae generaHistorical confusion arose from mistaking intraspecific variation in Probole amicaria for intergeneric differences; other geometer moths with variable wing patterns were previously conflated with this .
Misconceptions
The was long considered to contain multiple (P. amicaria, P. alienaria, P. nepiasaria). This was incorrect; all represent a single, highly variable species.

Taxonomic history
The 2007 revision by Rindge and colleagues used three independent lines of evidence—, mitochondrial (COI), and larval development—to demonstrate that Probole amicaria encompasses all previously recognized in the . This represents one of the more dramatic examples of taxonomic consolidation in North American Lepidoptera.
