There are about 70
species, all of which are found in the forests of the Afrotropics.
are similar in appearance to Bebearia
but are generally smaller, and their hindwings are deeper and
with a straighter costa. On the upperside the males of some species
e.g. coerulea and
aridatha are very dark, with a vague metallic steely-blue
sheen. Others e.g. lysandra and
gambiae have a reddish-brown ground colour. All
Euriphene species have well defined
dark bars in the cell of the forewings. Many also have a series of
small white dots arranged in an arc at the apex.
obani and gambiae have a
Catuna-like pattern of brown and cream.
Most other species including aridatha

The lifecycle of
to be unknown
but the following generalisations apply to the genus
Euriphene: Several species are known to
use Combretaceae as larval foodplants. The larvae have long
multi-branched lateral spines. Pupation takes place at the end of a
twig. Prior to pupation the larva spins a silk web on the twig and
wets it with a noxious yellow fluid which deters ants.
sexes tend to be
found along the narrower trails where sunlight filters through the
canopy to ground level.
