Nymphalidae

Nymphalidae is a large butterfly family whose adults have reduced forelegs that are not used for walking. Its members include monarchs, admirals, fritillaries, and morphos.

Lepidoptera: The insect order comprising butterflies and moths, typically distinguished by wings covered in scales. Nymphalidae is one of the largest families within this order.
Butterfly life cycle: The sequence of egg, larva, pupa, and adult stages through which butterflies develop. Nymphalids pass through complete metamorphosis like other butterflies.
Monarch butterfly: A milkweed-feeding butterfly known for long-distance seasonal migration in North America. The monarch is a conspicuous nymphalid with a celebrated multigenerational migration.
Butterfly migration: Seasonal movement by butterflies between regions, sometimes spanning multiple generations. Several nymphalids migrate long distances, offering cases for studying movement and navigation.
Phylogenetics: The study of evolutionary relationships among organisms using inherited traits and genetic data. Phylogenetic methods test how nymphalid subfamilies and tribes are related.
Butterfly: A day-flying insect in the lepidopteran group, usually with clubbed antennae and brightly patterned wings. This broader group includes all brush-footed butterflies.
Butterfly wing: A membranous insect wing covered with overlapping scales that create color and pattern. Nymphalid wing patterns often serve in concealment, signaling, and defense.
Red admiral: A widespread migratory butterfly marked by red-orange bands across dark wings. This familiar nymphalid illustrates the family’s broad geographic reach.
Batesian mimicry: A form of mimicry in which a harmless species resembles a defended or unpalatable species. Some nymphalids gain protection by resembling distasteful species.
Molecular systematics: The use of molecular data to infer relationships and classification among organisms. DNA evidence has reshaped parts of the family’s traditional classification.
