Globitermes sulphureus is a species of termite that is very common in central and southern Vietnam and also present in other areas of South East Asia, including Cambodia, Thailand, and Peninsular Malaysia. They live in nests made of earth that can be up to 1.5 m tall and can contain tens of thousands of individuals. Between five and 10 per cent of the population are soldier termites which can be recognised by their yellow abdomen and two large, curved mandibles. The termites use autothysis as a defense mechanism.
When the nest is damaged, the soldier termites defend the nest and workers rapidly repair any damage to the nest walls. The soldiers stand on alert on their legs and scan the area with their antennae. If the nest is attacked by ants, for example Oecophylla smaragdina, the workers immediately escape by retreating into the nest, while the soldiers remain outside to defend the nest. They will first attempt to catch and pierce the attackers with their large mandibles. If this does not deter the attackers, some soldiers secrete a yellow liquid from a large gland that occupies a large proportion of their body. The liquid is forced out of the gland by contractions of... Wikipedia →

With luck
About 10% of wildlife watchers report a Globitermes sulphureus sighting in Khao Yai National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 115th most-seen of the 221 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April, June and November
In those months about 20% of wildlife watchers report a Globitermes sulphureus in Khao Yai National Park on a given day, against under 5% in February–March, May and July–October, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Globitermes sulphureus sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Khao Yai National Park, in our data
Khao Yai National Park is the only park on Wallace's Line with enough records to rate Globitermes sulphureus sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Globitermes sulphureus is recorded against all the insects logged in Khao Yai National Park (7 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.
