The Red-lined Looper Moth or "Red-lined Geometer", Crypsiphona occultaria, is a moth of the Geometridae family, Lepidoptera Order of Hexapoda Arthropods (six legged insects). It is one of the most common moths found in Australia. The “red-lined’ part of the name refers to the red markings seen on the undersides of the wings. As larvae they are green and feed on eucalypt leaves. When threatened the grub stands still, pretending to be a stick (Zborowski & Edwards, 2007).
