Migration

The migration of the European subspecies of the Red Admiral , Vanessa atalanta atalanta, is well-documented from observations in Great Britain (Baker, 1968; 1969; 1972) and Italy (Benvenuti et al., 1994, 1996). Unanswered questions about Red Admiral migration nevertheless persist. It is not known whether individual Red Admirals migrate all the way from the northern to the southern end of their range, or whether they only fly part of the way. It is also unclear what proportion of the butterflies in different locales hibernate rather than migrate to warmer regions, or whether or not they can successfully overwinter in particular locations. The Red Admiral ranges widely over both Europe and North America and migrates seasonally (Opler and Krizek 1984, Larsen 1993). There should be little opportunity for smaller, isolated populations to develop under such conditions. Nevertheless, Red Admirals in Italy (Benvenuti et al. 1994, 1996) seem to have a different way of orienting to the sun and maintaining course during the autumn migration than do those of Britain (Baker 1968), which suggests some regional differences between populations.
