Photo Gallery and Species Biology

Most other species lack the dentate forewing termen. Very similiar to A. sericeus however the ground colour in that species is a much deeper violaceous-grey and more variegated in brown. The inner arm of the discal FW λ pattern of A. sericeus is much more distinct.
 Very similar and easily confused with Acosmeryx sericeus. Upperside of body and wings more uniform in colour, much less variegated in with grey and chestnut than in Acosmeryx sericeus. Thorax underside more olivaceous than in Acosmeryx sericeus. Abdomen underside less bright tawny than in Acosmeryx sericeus. Forewing upperside with brown, curved, antemedial band less extended than in Acosmeryx sericeus, the two lines that form it being separate for the greater part; first discal line narrow, broken at the veins, as are the subsequent lines; the bars between veins CuA1 and CuA2 of lines 3 and 4 heavier and closer together, often forming a single patch; an oblique band present, positioned as in Acosmeryx sericeus, narrower anteriorly, somewhat dilated distad at vein M2. Both wings undersides with costal margins less marked than in Acosmeryx sericeus, and the tawny colour more restricted and less bright. Hindwing upperside with dark discal and submarginal bands present, as in Acosmeryx sericeus. Hindwing underside with a distinct white line at the distal border with, as in Acosmeryx sericeus, widest between veins M2 and M3, not just at M2 (Sphingidae Taxonomic Inventory, 2021).
