monarch-butterfly

The monarch butterfly is a milkweed-dependent species whose black, orange, and white patterned wings make it one of the most recognizable pollinators in North America. Because monarch caterpillars feed exclusively on milkweed foliage, their life cycle is intricately tied to the chemistry and availability of these host plants, making them a key model for studying plant-insect coevolution and toxin sequestration. Research into this relationship also informs plant science on pollination ecology, herbivory defense mechanisms, and the conservation of native plant species that support specialist insect populations.
