The Iberian marbled white replaces the
marbled white in Spain, Portugal and the South of France. Like that
species, it is a familar and common butterfly of flowery grassland
throughout its range, flying in a single brood from June until August.
The grassland in question, of course, is not the lush, verdant meadows
of milder climes but the dry, prickly prairies of the South. It flies
in association with Spanish and southern gatekeepers, Spanish chalkhill
blues and false graylings - all species that conjure up the smell of
It is similar in appearance to the marbled white but has considerably
less dark at the base of the upperside forewings (the cell is clear at
the base) and lacks any dark discal markings on the upperside hindwing
- these being reduced to a 'bootstrap' along the lower vein of the
cell. Occasionally, the underside hindwing is all white. This is form cataleuca and corresponds to the form leucomelas in marbled white.
The life history is similar to that of marbled whites. The caterpillars
feed on various grass species and hibernate while relatively small,
completing their development in the spring.
