The name "White Grass Yellow" might sound like a
contradiction in terms, but signifies that most other members of
this genus are yellow, and live in grassy habitats.
Eurema are found in Africa, Asia and
the Australian region as well as in the neotropics. There are 19
species in the neotropical region, 5 of which are whitish on the
upperside, but only albula has a white
underside - the others are cream or yellowish beneath.
Both sexes of albula
have pure white uppersides. The apex and the outer margins of the
forewing are black in both sexes.
Eurema albula occurs from Mexico to
Uruguay, and on most Caribbean islands.
Like most other Eurema species this
breeds in disturbed semi-open forest edge habitats, which may
include roadsides, riverbanks, secondary forest and farmland. It
occurs at altitudes between sea level and about 1600m.
The eggs are laid singly on
Cassia ( Caesalpinaceae ).
fully grown caterpillar has a granulated texture, and is pale green
above and yellow below, with a white line along each side. The
chrysalis is pale green with a dorsal keel and a pointed head.
The butterfly is usually
encountered singly in disturbed forest edge habitats.
Both sexes nectar at low
growing flowers and at Lantana bushes.
Unlike most other Eurema species, the
males do not normally mud-puddle or visit sandbanks.
