See Also
Other Furcula species. The "monkey face" pattern on borealis is much more distinct than in the other Furcula, which often have much more or less black scaling and orange scaling, obscuring the "monkey face" pattern. F.borealis can be distinguished from pale occidentalis specimens, by the lack of a triple PM line, which is present in occidentalis and the darker thoracic scaling of occidentalis: more black scaling in the "monkey face," and gray - as opposed to white in borealis - scaling on the rest of the thorax.
