Queen (Danaus gilippus) lives in open savanna across Southwestern United States, Mexico, Central America. Its conservation status is Least Concern.
Fascinating facts about the Queen
- A queen female may mate up to 15 times in a single day, far more than most butterflies. Males patrol all day, then hover and brush their abdominal hair-pencils against the female's antennae, releasing pheromones that trigger receptivity. Experiments show that removing these hair-pencils dramatically lowers male success, proving the structures are essential tools for chemical courtship, even though they are not needed for the act of copulation itself.
- Queens are distasteful to birds when their larvae feed on high-cardenolide plants like Asclepias curassavica; those individuals store toxin levels comparable to monarchs and are usually rejected. When raised on low-cardenolide hosts such as S. clausum, they contain no detectable cardenolides and become essentially palatable. This plant-driven chemical spectrum means that even neighboring populations can differ dramatically in predator protection, shaping local mimicry dynamics.
- The queen butterfly inhabits a belt from Brazil up through Florida, the Gulf Coast, and the southwestern United States, with regular sightings in peninsular Florida, southern Georgia, Texas, New Mexico, Arizona, and California, and occasional strays as far north as Kansas and Utah. Its presence from tropical Central America down to Argentina shows a remarkable ability to thrive in both desert-like dunes and lush meadow edges, highlighting its adaptability to diverse open-land habitats.
- A queen butterfly stretches its wings to a span of 80-85 mm, about the length of a small ruler, while the average adult measures roughly 3 inches across.
- A female queen lays a single, pale-green egg at a time on the leaves, stems, or flower buds of milkweed relatives, each egg shaped like a tiny cone with a flattened base and ribbed surface.
