The monarch population in Florida may be a result from migratory butterflies that do not migrate north in the spring. [47] [45] These locations provide access to nectar plants. If there is a hard frost in these areas they do not survive.
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 ...
These wasps lay their eggs in the pupae while the chrysalis is still soft. Up to 400 adults emerge from the chrysalis after 14–20 days, [186] killing the monarch. The bacterium Micrococcus flacidifex danai also infects larvae. Just before pupation, the larvae migrate to a horizontal surface and die a few hours later, attached only by one pair ...
These butterflies migrate in the fall, This fascinating insect goes through an amazing life cycle consisting of four stages: egg, larvae, pupa, and adult. Some monarch butterflies migrate each ...
As displayed in an illustration by the U.S. Geological Survey, in wetter conditions, butterflies lay fewer eggs, while warmer temperatures hinder the growth of milkweed is hindered by warmer ...
[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.

Threats to the monarchs include the loss and degradation of habitat used for breeding, migration and overwintering, including milkweed plants they rely on as a place to lay their eggs.
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 ."
