This suggests that butterflies migrating along the eastern seaboard are migrating to locations other than Mexico, or they have a higher rate of mortality than those migrating inland. [20] Monarch butterflies are thought to respond to different cues that promote the fall season southern migration.
The eggs weigh less than 0.5 mg (0.0077 gr) each and have raised ridges that form longitudinally from the point to apex to the base. Although each egg is 1 ⁄ 1000 the mass of the female, she may lay up to her own mass in eggs. Females lay smaller eggs as they age. Larger females lay larger eggs. [30]
The butterflies lay their eggs on the milkweed, and when caterpillars hatch, they feast on the plant’s leaves. There are more than 20 species of milkweed native to Florida, less than half of ...
[54] [55] As a result of these factors, reproducing monarchs lay fewer eggs on A. tuberosa than they do on most other milkweeds. [54] [51] While the plant's colorful flowers provide nectar for many adult butterflies, A. tuberosa may therefore be less suitable for use in butterfly gardens and monarch waystations than are other milkweed species.

A new report shows a sharp decline in monarch butterflies migrating to Mexico as well as a loss of habitat in the forests they spend their winter each year.
There are several historic records about migrating butterflies. There are records dating back to 1100 about migrating butterflies (probably a Pieris species) from Bavaria to the Duchy of Saxony and from 1248 about the migration of yellow butterflies in Japan. When flying at high altitudes, spotting migrating butterflies or moths can be hard.
The butterflies cling in clusters on tree branches, especially pine and eucalyptus groves where they can be somewhat sheltered from the wind and rain and wait for the temperatures to warm above 60 ...
Monarch Watch is a volunteer-based citizen science organization that tracks the fall migration of the monarch butterfly. [1] It is self-described as "a nonprofit education, conservation, and research program based at the University of Kansas that focuses on the monarch butterfly, its habitat, and its spectacular fall migration ."
