Little is known about the biology of the fabulous green sphinx moth. Like all Lepidoptera (moths and butterflies), it has a long, coiled proboscis, which is most likely used for feeding on nectar (3).
Records show that the fabulous green sphinx moth may lay around 15 eggs at a time but, after nine days, just a few of these will hatch into caterpillars (2). These caterpillars then feed, probably on plants, until they undergo a full metamorphosis into an adult (3). Efforts to identify the plant on which this species feeds have, to date, been unsuccessful (2).
The fabulous green sphinx mothhas been captured repeatedly near light sources suggesting it may have a strong attraction to light (2).
