Heteropteryx is a monotypic genus of stick insects containing Heteropteryx dilatata as the only described species. and gives its name to the family of the Heteropterygidae.

It originates from the Malay Archipelago and is nocturnal.
The females are much larger and wider than the males, reaching 14 centimetres (5.5 in) to 17 centimetres (6.7 in) in length and 30 to 65 g in weight, making them among the heaviest phasmids and extant insects.

At rest, the green forewings, formed as tegmina, cover the somewhat shorter, strikingly pink-colored membranous hind wings, here formed as alae, however they are incapable of flight. The head, body and legs are thorny. The flattened body is provided with a number of spines, in particular along the body edges including the abdomen and the legs,... Wikipedia →

Possible
About 20% of wildlife watchers report a Malayan Jungle Nymph sighting in Khao Sok National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 104 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
June and July
In those months about 40% of wildlife watchers report a Malayan Jungle Nymph in Khao Sok National Park on a given day, against under 5% in August and October–December, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Malayan Jungle Nymph sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Khao Sok National Park, in our data
Khao Sok National Park is the only park on Wallace's Line with enough records to rate Malayan Jungle Nymph sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Malayan Jungle Nymph is recorded against all the insects logged in Khao Sok National Park (19 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.
