Xylophanes pluto

The broad chrome-yellow band on the forewing is diagnostic and separates Xylophanes pluto from all other species in the genus. The combination of green thorax, maize yellow abdomen with metallic yellow scaling, and interrupted medial line with segmental dots provides additional distinguishing characters. Wing shape and body proportions typical of Xylophanes hawkmoths.

Medium-sized hawkmoth with wingspan 53–65 mm. Forewings display a prominent broad chrome-yellow band that distinguishes this species from all other Xylophanes. Thorax green. Abdomen with thin medial line interrupted at base of each segment by metallic yellow dot; lateral lines present. Thorax and abdomen maize yellow with metallic yellow scales; a few metallic yellow scales also present dorso-laterally.

Tropical and subtropical lowlands. In the United States, restricted to southern Florida and southern Texas. Occupies diverse lowland habitats throughout its range including forest edges, gardens, and disturbed areas where host plants occur.

Native to the Americas. Range extends from Argentina and Paraguay north through Bolivia and tropical/subtropical lowlands of Brazil, continuing through Central America to Mexico, the West Indies, southern Florida, and southern Texas. Distribution records confirmed from multiple Brazilian states including Amapá, Distrito Federal, Espírito Santo, Maranhão, Minas Gerais, Mato Grosso, Pará, Paraíba, Pernambuco, Paraná, Rio de Janeiro, Roraima, Rio Grande do Sul, Santa Catarina, and São Paulo.

Multiple generations per year in Florida and Texas. Adults active year-round in tropical portions of the range.

Larvae feed on Chiococca species, Erythroxylum species, Hamelia patens (firebush), and Morinda royoc. Adult feeding habits not specified in available sources.

• Chiococca - larval foodplantgenus in family Rubiaceae
• Erythroxylum - larval foodplantgenus in family Erythroxylaceae
• Hamelia patens - larval foodplantcommon name firebush, family Rubiaceae
• Morinda royoc - larval foodplantfamily Rubiaceae

Multiple generations per year in temperate portions of range (Florida, Texas). Continuous breeding with year-round adult activity in tropics. Complete metamorphosis with egg, larva, pupa, and adult stages; specific details of pupation and overwintering not documented in available sources.

Adults are nocturnal. Flight behavior typical of sphingid moths with rapid, agile flight. Specific behavioral details beyond flight activity patterns not documented in available sources.

Adults likely serve as pollinators. Larvae function as herbivores on their specific host plants. Role in food webs as prey for birds, bats, and other insectivores inferred from family-level traits but not specifically documented.

Occasional visitor to gardens in southern Florida and Texas where larval host plants are cultivated. No significant economic importance documented. Subject of interest to lepidopterists and naturalists.
