Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang

Found in tropical forests, plantations, and forest clearings throughout Central and South America.

BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang

Adults feed on overripe fruit, tree sap, and sometimes animal droppings.

Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang

Generally solitary, but often found in clusters around food sources.

Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang

Frugivore (adults).

Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang

Larvae are specialists on monocots; adults are generalist scavengers of fermenting organic matter.

Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang

Females lay eggs singly or in small clusters on the underside of host plant leaves.

Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang

Larvae are known pests on banana and oil palm plants, utilizing these crops as highly abundant food sources.

Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang

While considered a pest in agricultural settings, its natural habitat is threatened by general tropical deforestation.

Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang

They are predominantly crepuscular, often being most active during the low-light periods of dawn and dusk.
