Definition
Eurytides dolicaon is a species of butterfly in the family Papilionidae, commonly referred to as the Dolicaon swallowtail.
Overview
The Dolicaon swallowtail is a Neotropical butterfly native to parts of Central and South America. Its range includes countries such as Colombia, Ecuador, Peru, Brazil, Bolivia, and Venezuela, where it inhabits tropical and subtropical forested areas, often at low to mid elevations. The species is part of the genus Eurytides, which comprises several large, white‑colored swallowtails characterized by elongated hindwing tails.
Etymology/Origin
The genus name Eurytides derives from Greek roots: “eurys” meaning “broad” and “tides” meaning “wing”, referencing the broad wings of species within the group. The specific epithet dolicaon is a reference to Dolicaon, a figure in Greek mythology, although the original describer’s rationale for this name has not been explicitly documented in accessible literature.
Characteristics
-
Morphology: Adults possess a wingspan typically ranging from 80 to 100 mm. The dorsal wing surfaces are predominantly white with black marginal bands and a series of pale yellow or greenish spots near the apex of the forewings. The hindwings exhibit pronounced, spatulate tails. Ventral surfaces are similar but may display additional reddish or brownish markings.
-
Life cycle: Like other papilionids, E. dolicaon undergoes complete metamorphosis (egg → larva → pupa → adult). Eggs are laid singly on host plants. The caterpillars are greenish with lateral stripes and possess a characteristic osmeterium—an eversible scent organ used for defense. Pupation occurs in a silk‑enclosed chrysalis attached to foliage or among leaf litter.
-
Host plants: Larvae feed on members of the family Annonaceae, particularly species of the genus Annona (e.g., Annona muricata). This plant association is typical for many Eurytides species.
-
Behavior: Adults are fast, strong fliers and are often observed patrolling forest edges and clearings. Males may exhibit mud‑puddling behavior, extracting minerals from moist substrates.
-
Conservation status: The species has not been evaluated by the International Union for Conservation of Nature (IUCN). However, habitat loss due to deforestation in parts of its range could potentially impact local populations.
