The adult moth has forewings with brown and silvery white longitudinal stripes. The hind wings are silky and buff coloured. However, when the moth is holding onto a vertical blade of grass with its wings wrapped around its body, the shiny stripes make a good camouflage. The moth has a wing span of about 3 cms.
