of the genus Pontia is contentious with
some authorities considering there to be as many as 10 species,
while others regard edusa and
chloridice to be subspecies of
daplidice or mere synonyms of that
species. Further confusion arises because the Peak White
Synchloe callidice is also included in
Pontia by many workers.
Pontia is represented in all continents
except North America and Australasia. The most widespread and
abundant species is daplidice. It
occurs in Morocco, Algeria, Tunisia, the Canary Islands and over
most of Europe. If edusa and
chloridice are included within the
definition of daplidice the range is
greatly extended and also covers Ethiopia, Iran, northern India and
most of temperate Asia. The butterfly is also recorded as a rare
vagrant in southern Britain.
inhabits open hot and often barren areas where its larval foodplant
flourishes. It is most abundant at low altitudes in Europe, but has
been found as high as 2700m in north Africa.
The most widely used larval foodplant is Reseda
( Resedaceae ) but Sisymbrium,
and Raphanus ( Brassicaceae ) are also
used. The eggs are usually laid singly on the underside of leaves but
the larvae feed on the flowers and developing seedpods.
The butterflies are only active in hot sunshine when they nectar
avidly at a wide range of flowers.
