Lepidopteran Migrations in 1969

Abstract

1969 was a good year for butterflies; the common species seemed more plentiful than usual and the rarer ones less rare. Among the abundant ones were the Yellow Migrant Phoebis statira (Cramer), and the White-tailed Page, Urania leilus Linnaeus, a day-flying moth. Both migrated in considerable numbers. Since butterfly migrations are not easy to study and all observations are valuable, I record here my observations on the two species.
