Eurema was until fairly recently
represented in the neotropics by about 30 species, but several have
now been reclassified as Pyrisitia,
leaving a total of 19 currently recognised species in the
neotropical region. Elsewhere in the world the genus has 9 species
in Africa, 2 in Madagascar, and 9 in the Oriental and Australian
These smallish butterflies are characterised by
having yellow or white uppersides, with dark apical markings. The
forewings have a strongly curved costa and a squarish apex. The
hindwings are rounded in most species, but in
salome, xantochlora and
arbela the termen is projected to a
point. The various species can be told apart by the pattern of
mottled dark markings on the underside hindwings, and by the black
borders on the upperside forewings, which differ according to
Eurema salome is distributed from Mexico to Peru.
This is a pre-montane cloudforest species, occurring along roadsides
and forest edge habitats.
The eggs have only been recorded on Fabaceae. Other
Eurema species oviposit on Mimosaceae,
Caesalpinaceae and Simaroubaceae, as well as Fabaceae, so it is
possible that these families could be utilised also by
salome. I have no data regarding the
early stages of salome but
Eurema larvae are typically dull green
with a whitish line along the sides, and a rough texture.
Eurema pupae are pale green or
yellowish, and have a prominent keel.
are usually encountered singly, or occasionally in two's or three's,
seen imbibing dissolved minerals from damp ground at the edge of
ditches, runnels or roadside banks in forested areas.
are more often seen nectaring at flowers along roadsides and
riverbanks, or when exploring sunny wood edge habitats in search of
The flight is fluttery but fairly
rapid, and always close to the ground.
