Taxonomy
The species is considered to form a superspecies complex that includes Actias ignescens Moore 1877 from the Andamans, Actias isis (Sonthonnax 1897) from Sulawesi, and Actias groenendaeli Roepke 1954 from Flores, Timor and Sumba. Actias rosenbergii (Kaup 1895) from Ambon is of doubtful status. This species is further divided into subspecies with the nominate from Continental Asia and A. m. diana Maassen 1872 from Sundas and in the Philippines.
Range
The Malaysian moon moth ranges from Malaysia, to Sumatra, Java, the Philippines, and the surrounding region in Southeast Asia and South Asia including a population in the Western Ghats. This species covers a diverse set of biomes, from tropical rainforests to evergreen forests.
Life cycle
Larvae rest in a position where the anterior end of the body is held free of the substrate, such as a leaf or a stem. Males finish development a few days earlier than females in larval and pupal stages because they are smaller. Pupae are dark brown with a transparent window area between compound eye covers. Cocoons are irregular in shape and have a papery texture. They are light brown with a glossy sheen, and have a pre-formed exit opening at the anterior end. Adults push out of their flimsy cocoons with ease. 45 minutes after emergence, wing expansion is complete. Once the forewings have completely expanded, tail expansion begins. Females fly after their wings have hardened. Unlike most Saturniidae females, these emit pheromones and mate after their first flight.
Sexual dimorphism
Adult Actias maenas exhibit striking sexual dimorphism. Adult males are bright yellow and have purplish-brown markings, while adult females are light green in color.
