Biblidinae are known for their diverse but simple and colourful
patterns. In the neotropics their representatives include the

Dynamine species have highly reflective
bluish or greenish uppersides, often in combination with a dark apex
and borders. Dynamine postverta is
easily recognised by the group of 4 squarish dark spots on each
forewing. The underside is similar to that of other
Dynamine species, being white, marked
with narrow bands of orange. In common with several other species
there is also a pair of blue-centred submarginal ocelli on the
( previously known as
) is the commonest and most widespread member of the genus, being
found throughout most tropical and subtropical areas of central and
South America, from Mexico south to Argentina and Paraguay.
This species is found in a wide variety of habitats including
primary rainforest, humid deciduous woodlands, scrubby grassland,
farmland etc; at altitudes between sea level and about 900m.
The eggs of most
species are white. They are laid singly on the leaf axils or flower
buds of Euphorbiaceae genera such as
larvae are described by DeVries as being slug-like, with tiny
rosettes of spines on the back. The pupae are greenish, elongate,
with a slightly bifid head and a pronounced dorsal keel, and
suspended by the cremaster from stems or leaves.
are very active in hot sunny conditions, when they can be seen flying
rapidly in zig-zag fashion, investigating along forest tracks. In the
cooler temperatures of early morning they can often be found basking
on foliage, usually with their wings held half-open.
Males visit dry
river beds, and damp ground along sunlit forest tracks and roads. They
habitually flick their wings open while moving about in a fairly
erratic fashion as they probe for minerals on the ground.
