The Ilima Moth (Amyna natalis) is a moth of the Noctuidae family. It is widespread from tropical Asia into northern Australia. It is an introduced species in Hawaii, where it is found on Oahu.

Description

The wingspan of male is 20mm and female 26mm. Body dull brown. Fore wings with indistinct sub-basal, antemedial, postmedial and sub-marginal single waved lines with a few grey scales on them. Reniform represented by a small spot. Abdomen and hind wings are fuscous. Abdomen with an indistinct postmedial line.[1]

Waltheria americana

Ecology

Larvae have been recorded on Abutilon incanum, Sida cordifolia, Sida fallax, Sida rhombifolia and Waltheria americana. The caterpillars are green loopers.[2]

Bioacoustics

Males have been observed producing a continuous ultrasonic song of high intensity (about 102 dB SPL measured at a distance of 10 cm). During song production the animals were perching on plants and moving their wings up and down quickly. Simultaneously, by twisting the wings it seems likely that a male-specific bubble in the forewing functions as a tymbal, resulting in sound production. The sound production may be associated with the release of a pheromone from putative scent-disseminating structures on the underside of the forewing tymbal.[3][4]
