Pollen analysis were carried out on moths [Agrotis (Scotia) ipsilon] c
ollected on two sites in south-east France, one near the Mediterranean
sea (Camargue), the other in the Alps, at 2000 m altitude. A spring m
igration from east and south-east (Corsica and the French Riviera) was
found at the Camargue site, while a possible fall migration from the
North (Lyon area) appeared in the Alps. In addition, the analyses indi
cate that moths visit certain nectariferous floral sources.
