Explanations –

Statement 1 is correct. Painted lady butterflies undertake an annual multi-generational migration between Europe and North Africa, covering vast distances, including crossing the Sahara Desert to reach breeding and wintering grounds in Africa before returning to Europe in spring.

Statement 2 is incorrect. Unlike some migratory species, painted lady butterflies do not return to the same breeding place each year. Their migration is a continuous process involving multiple generations, with successive generations breeding and moving along the migration route rather than returning to a specific location.
