Megjegyzések:	This species has a Mediterranean distribution with variable annual population size. Usually this butterfly does not occur in large numbers, but in 2010 it appeared in invasionary magnitudes in April for several weeks in the whole of Hungary. The reasons behind this phenomenon is provided by the author, hypothesising that population increase of this butterfly was facilitated by increasing trends in precipitation in African areas leading to larger vegetation biomass. As a likely result of a sudden drought and heat, masses of simultaneously transformed butterflies migrated to the northern parts of Europe in searching for areas providing nectar supplies and locations for oviposition. The author has worked intensively with the biology of the species controlled by laboratory rearing of caterpillars.
