Another study found that this species has another characteristic which makes it vulnerable to extinction: it is not only a dietary specialist, also migrates only small distances. This creates problems for the species, since fragmentation most strongly affects animals that migrate short distances and are unable to cross the gaps made by human habitat destruction. While long distance migratory species are often unaffected and sedentary species are often able to better use the fragments they are in, short distance migrators like the small pearl-bordered fritillary are unable to properly disperse and are hit hardest from environmental damage.
