[1] [dubious – discuss] Their development is closely linked to the evolution of flowering plants, since both adult butterflies and caterpillars feed on flowering plants. Of the 220,000 species of Lepidoptera, about 45,000 species are butterflies, which probably evolved from moths. Butterflies are found throughout the world, except in ...
Monarch butterflies are thought to respond to different cues that promote the fall season southern migration. These include the angle of light coming from the sun, the senescence of larval host milkweed plants, the decreasing day period and temperature drop. [21] The migration begins at the northernmost summer range approximately in August.
[239] [240] The plant's low levels of cardenolides may also deter monarchs from laying eggs on the plant. [241] While A. tuberosa 's colorful flowers provide nectar for many adult butterflies, the plant may be less suitable for use in butterfly gardens and monarch waystations than are other milkweed species.

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.
Millions of butterflies arrive in the reserve annually. Butterflies only inhabit a fraction of the 56,000 hectares of the reserve from October–March. The biosphere's mission is to protect the butterfly species and its habitat. Most of the overwintering monarchs from eastern North America are found here. Researchers discovered these areas in 1975.
The butterflies are abundant in late summer, despite many of the native shrubs losing their blooms. There are still plenty of flowers: small violet bouquets at the tips of De La Mina verbena ...
