The Mexican Longwing Butterfly is native to southern Mexico and northern Central America. It is sometimes called the Mountain Longwing although it is not found only in mountain areas. It looks similar to the butterfly shown on this page but HAS WHITE BARS ON THE FOREWING instead of pink and they have a particular pattern that differs a little from those shown.
THOSE SHOWN HERE MAY BE HYBRIDS, A RELATED SPECIES OR A GOOD MIMIC THAT FLIES IN THE SAME REGIONS.
One related species that looks similar is Clysonymus Longwing (NOT SHOWN),
Heliconius clysonymus, which is less pink. It looks like an inverted Postman Longwing, with a red bar instead of white and white bars instead of red. It is also, strangely, called the Yellow Longwing, and is native to territory adjoining that of the Mexican Longwing, from southern Central America to northern South America. It has several subspecies. However, its red bar does not have such a "frayed" trailing edge and its white forewing bar is a totally different shape from the butterfly above, which
may be a hybrid or mimic of the Mexican Longwing.
The butterflies above have the right colour scheme for Mexican and Clysonymus Longwings
(Heliconius clysonymus) but the
white bars on the forewing are the wrong shape for either (and above right differs from above left/centre - possibly H. himera
or clysonymus). The white bars and the rayed red are also wrong for the Doris Longwing. They may be Postmen mimics flying in the same area or one of the Cydno family which also mimics red, rayed hind wings, a narrow white bar and no red on the forewing.
