Description
Gnathothlibus eras is a medium to large-sized hawkmoth. The forewings are typically an olive-brown or greyish-brown color, often with obscure darker markings or a faint pattern of lines. The hindwings are generally yellowish or orangish, usually with a dark outer margin or band, which can vary in prominence. The body is robust, characteristic of most hawkmoths, and shares the same general coloration as the forewings. The antennae are relatively thick and club-like.
Distribution and Habitat
This species is widely distributed across the Indo-Australian region. Its range extends from India and Sri Lanka through Southeast Asia, including Myanmar, Thailand, Laos, Vietnam, southern China, Malaysia, Singapore, and Indonesia. It is also found in Papua New Guinea, the Solomon Islands, and parts of northern Australia (particularly Queensland).
Gnathothlibus eras inhabits various environments, including tropical and subtropical forests, gardens, and agricultural areas where its host plants are present. It is a strong flyer and can be found in a diversity of habitats within its wide range.
Biology
Like many hawkmoths,
Gnathothlibus eras is nocturnal and strongly attracted to light. Adults are active at dusk and during the night, feeding on nectar from a variety of flowers.
The larvae, or caterpillars, are typically green or brown with characteristic false eye-spots on their segments, which can serve as a deterrent to predators. They are known to feed on plants from several families, including Araceae (such as
Colocasia and
Alocasia), Convolvulaceae, and sometimes other herbaceous plants. The pupation typically occurs in the soil or in leaf litter. The species is bivoltine or multivoltine in warmer climates, meaning it can have multiple generations per year.
