Ctenomorpha marginipennis, the margin-winged stick insect, is a species of stick insect endemic to southern Australia. The species was first described by George Robert Gray in 1833, then placed in the genus Didymuria by Kirby in 1904.
It was subsequently accepted as "Ctenomorpha chronus (Gray, 1833)". C. marginipennis resembles a eucalyptus twig and can grow up to 20 cm in length. The males are long and slender, have full wings and can fly. The females are larger with blackish hindwings. The wings of the females are smaller than those of the males. The legs and head (prothorax) are light pinkish brown, with the legs being dentated. The mesothorax, tegmina, abdomen and leaflets, are all blackish green. The mesothorax may have small tubercles. The abdomen contains numerous small spots. The cerci are extremely long and may be somewhat dentated. The nymphs are similar to the older stage, but with only small wing buds instead of the full-length wings of the adults. This species can be distinguished from other members of the family by their extremely long cerci and by the appearance of their eggs.

Possible
About 20% of wildlife watchers report a Margin-Winged Stick Insect sighting in Blue Mountains National Park on a given day, based on 115 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 789 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Margin-Winged Stick Insect is recorded against all the insects logged in Blue Mountains National Park (115 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
