Possible
About 20% of wildlife watchers report a Giant Tree Nymph sighting in Khao Luang National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 30th most-seen of the 36 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.
September
In that month about 60% of wildlife watchers report a Giant Tree Nymph in Khao Luang National Park on a given day, against under 5% in May–August, October and December–February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Giant Tree Nymph sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Khao Luang National Park, in our data
Khao Luang National Park is the only park on Wallace's Line with enough records to rate Giant Tree 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 Giant Tree Nymph is recorded against all the insects logged in Khao Luang National Park (5 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.
