Long-term springtime counts of immature and adult monarch butterflies and their Asclepias humistrata host plants in north-central Florida reveal a close relationship between the milkweed's phenology and the butterfly's spring remigration from Mexico. Remigrant adults arrive after most frosts occur and as the milkweeds are flourishing but before the plants begin to senesce. The peak of adult arrival is during the first few days in April; the eggs that are laid during this peak develop through Apr...

Selective pressures that occur during long-distance migration can influence morphological traits across a range of taxa. In flying insects, selection should favour individuals that have wing morphologies that increase energy efficiency and survival. In monarch butterflies, differences in wing morphology between migratory and resident populations suggest that migratory populations have undergone selection for larger (as measured by length and area) and more elongated (as measured by roundness and...

Monarch butterflies ( Danaus plexippus ) conduct one of the most spectacular migrations in the animal kingdom. Across generations, populations move between their 3,375,000 km2 breeding range in the United States and Canada and the much smaller patch of forest in central Mexico where they spend the

To assess the change in the size of the eastern North American monarch butterfly summer population, studies have used long-term data sets of counts of adult butterflies or eggs per milkweed stem. Despite the observed decline in the monarch population as measured at overwintering sites in Mexico, these studies found no decline in summer counts in the Midwest, the core of the summer breeding range, leading to a suggestion that the cause of the monarch population decline is not the loss of Midwest ...

Addressing population declines of migratory insects requires linking populations across different portions of the annual cycle and understanding the effects of variation in weather and climate on productivity, recruitment, and patterns of long-distance movement. We used stable H and C isotopes and geospatial modeling to estimate the natal origin of monarch butterflies (Danaus plexippus) in eastern North America using over 1000 monarchs collected over almost four decades at Mexican overwintering ...

ABSTRACT. The effects of mowing milkweeds in areas visited by monarch butterflies (Danaus plexippus L., Nymphalidae) were studied by counting the eggs and larvae on regenerating common milkweeds (Asclepias syriaca L., Apocyanaceae) in five adjacent mowed hayfields in northern Virginia in late summer 2015. At the same time monarch larvae were counted on mature senescent common milkweeds in unmowed areas adjacent or near to the mowed hayfields. Milkweeds supported populations of immature monarchs ...
