Habitat & Geographic Range

Common Buckeye

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Canada and United States.

Epaulard

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador, Venezuela).

Common Buckeye

The common buckeye (<em>Junonia coenia</em>) is a strikingly patterned butterfly found across North America, with documented occurrences in Canada and the United States. This species typically inhabits all terrestrial and freshwater environments across its range, favoring open, sunny habitats such as meadows, fields, roadsides, and coastal areas with low vegetation. It is classified as Least Concern on the IUCN Red List, reflecting stable and widespread populations. As a member of the family Nymphalidae, the common buckeye is instantly recognizable by the large, colorful eyespots on both the fore- and hindwings, which serve as a defense mechanism against predators. Larvae often feed on a variety of host plants in the families Plantaginaceae and Acanthaceae. The common buckeye typically undertakes seasonal migrations, moving southward in autumn and returning north in spring. Adults often nectar on a wide variety of wildflowers throughout their active season. Biological traits of this species remain poorly documented in the scientific literature.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
