silky owl butterfly

This is one of the silky owl butterflies (Taenaris). This specimen has different eyespot markings than the most commonly seen species at this location (Taenaris cf. catops). "The species of Taenaris are whitish to grayish, some species with a yellow anal margin on the hindwing, and with prominent eyespots displayed on the hindwings. Some species feed on cycads and may be chemically defended, serving as models for Batesian mimicry in a variety of other groups (including Hyantis, Mycalesis, Hypocysta, Elymnias, and Hypolimnas). Most species occur in New Guinea and surrounding islands." (EOL). Based on an illustration in van Mastrigt et al (2010) and a corroborating comment below (by Jeff), I am going to call it T. dimona. However it is important to note that "Only in a few cases is identification to species possible from the pattern of the ocelli since these can be highly variable. All [species] are diurnal but appear to prefer the shade, feeding on rotten fruit on the forest floor." (Gotts and Pangemanan, 2001).
