Explanation of Names
Subspecies jamapa enters the U.S.
Yellow; hind wings angled / "tailed" with "tails" broad, short and triangular; upper side with bold black border along outer edge of all four wings in males and front wings in females; dark spot at outer end of forwing discal cell is present on under side but absent or only faintly indicated on upper side.
Most likely to be confused with E. mexicana which tends to be a paler yellow above, with the inner edge of the dark borders more irregular (forming a poodle-face outline on the front wings); with brownish diagonal streak across the under side of the hind wings (equivalent markings on E. salome broken into spots).
Eurema boisduvaliana is also similar, and also rather rarely encountered, but occurs over a broader area along the southern border of the U.S. from Florida to Arizona. While similarly usually bright yellow above, it has the apex of the front wings more rounded, a somwhat broader and more irregular dark border, and the underside is marked more as in E. mexicana, though often with the area beyond the diagonal dark hindwing streak contrastingly darker than the area toward the base from it.
Probably not resident north of Mexico, occasionally strays into Texas and s. New Mexico.
