This species, formerly
considered a subspecies of the brown argus, Aricia agestis,
replaces that species in Iberia, the Balearic Islands, Sardinia, North
Africa and the Canaries. Like its relative, it is generally a common
butterfly, though local, found in flowery places where its foodplants -
various species in the geranium family - grow.
most ways very similar to the brown argus, this species is brighter, on
upperside and underside, with complete arrays of large, orange lunules
upperside, merging into a single orange band in the Canaries. The only
place where confusion is likely to occur is on the French side of the
Pyrenees, where it is possible both species fly (I am not sure if there
is an overlap or a narrow band where neither flies). Otherwise, their
distributions are geographically disjunct.
The southern brown argus flies in a succession of broods from April
until September or October in Europe and is continuously brooded in the
Canaries, where it has been recorded in every month of the year. Where
it hibernates, it probably does so as a larva, like the brown argus.
