Pachylia ficus

Linnaeus, 1758

fig sphinx

Pachylia ficus, commonly known as the fig sphinx, is a in the Sphingidae. It occurs from Uruguay through Central America to the southern United States, with occasional strays into Arizona and Texas. feed on nectar and are documented of the endangered ghost orchid (Dendrophylax lindenii). Larvae feed on multiple Ficus and related plants in the Moraceae family.

Identification

The fig sphinx can be distinguished from similar sphingid by its orange-brown wing coloration and relatively large wingspan. It is the only in the Pachylia, which separates it from other sphingid genera. The specific association with Ficus plants provides additional identification context where larval stages are found.

Habitat

Associated with supporting Ficus , including tropical and subtropical forests, urban and suburban landscapes with ornamental fig plantings, and agricultural areas where figs are cultivated.

Distribution

South America from Uruguay northward through Central America, extending to the southern United States (Arizona and Texas as occasional strays). Documented in Brazil across multiple states (Acre, Alagoas, Amazonas, Amapá, Bahia, Ceará, Distrito Federal, Espírito Santo, Goiás, Maranhão, Minas Gerais, Mato Grosso do Sul, Mato Grosso, Pará, Paraíba, Pernambuco, Piauí, Paraná, Rio de Janeiro, Rio Grande do Norte, Rondônia, Roraima, Rio Grande do Sul, Santa Catarina, Sergipe, São Paulo, Tocantins), as well as Panama and Colombia (Villavicencio).

Seasonality

Multiple per year in tropical regions, peninsular Florida, and southern Texas. recorded in February, September, and November in Brazil; June in Panama.

Diet

feed on nectar of various flowers including Asystasia gangetica and Dendrophylax lindenii (ghost orchid). Larvae feed on Ficus aurea, Ficus carica, Ficus microcarpa, Ficus religiosa, Ficus pumila, Ficus gamelleira, Ficus prinoides, and Artocarpus integrifolius.

Host Associations

  • Ficus aurea - larval food plant
  • Ficus carica - larval food plant
  • Ficus microcarpa - larval food plant
  • Ficus religiosa - larval food plant
  • Ficus pumila - larval food plant
  • Ficus gamelleira - larval food plant
  • Ficus prinoides - larval food plant
  • Artocarpus integrifolius - larval food plant
  • Asystasia gangetica - nectar source
  • Dendrophylax lindenii - nectar sourceendangered ghost orchid; are documented

Life Cycle

Multiple per year in tropical and subtropical regions. hatch into larvae that feed on Ficus foliage. Larvae display several color morphs. occurs in a cocoon spun among leaf litter. emerge and feed on nectar, with activity documented across multiple months depending on region.

Behavior

are known of the endangered ghost orchid (Dendrophylax lindenii). Adults have been recorded feeding on nectar during February, June, September, and November across their range, suggesting extended or year-round activity in favorable climates.

Ecological Role

function as , specifically documented for the endangered ghost orchid. Larvae serve as herbivores on Ficus and related Moraceae , potentially contributing to nutrient cycling through their consumption of leaf material and subsequent in leaf litter.

Human Relevance

Larvae feed on cultivated fig (Ficus carica), potentially affecting commercial fig production. The species' role as a of the endangered ghost orchid has conservation significance. are occasionally observed in the United States (Arizona, Texas) as vagrant individuals.

More Details

Conservation significance

Documented pollination of Dendrophylax lindenii (ghost orchid), a federally in the United States, represents an important ecological interaction.
