Dorylus laevigatus is a member of the army ant genus Dorylus, or Old World army ants. More specifically known as "driver ants", the genus Dorylus is abundant throughout Africa and stretches into tropical Asia, where D. laevigatus is primarily found. They are a eusocial colony-forming species, which live primarily underground, rarely venturing to the surface for any reason. D. laevigatus colonies are small for army ants, estimated averages falling between 30,000 and 1,000,000 individuals.
Dorylus laevigatus shares the typical morphological characteristics common of all ants, including three body segments known as tagmata, a slim waist joining the second and third tagmata called the petiole, and mandibulate mouth parts located on the head for holding and breaking down food. Characteristic of their genus, D. laevigatus is blind, possessing no eyes and communicating entirely through pheromones. As a holometabolous insect, D. laevigatus larvae differ significantly from the mature adults, closely resembling white maggots.
D. laevigatus has a high degree of caste polymorphism, meaning that individuals within the species have radically different morphological characteristics... Wikipedia →

Rare
Under 5% of wildlife watchers report a Dorylus laevigatus sighting in Singapore on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 735th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dorylus laevigatus in Singapore on a given day, so our monthly data shows no clear season.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Dorylus laevigatus sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Formicidae
The closest relatives of the Dorylus laevigatus that you can see in Singapore (family Formicidae, Ants) are Asian Weaver Ant (about 20%), Cocoa Black Ant (about 10%) and Common Oriental Trap-Jaw Ant (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dorylus laevigatus is recorded against all the insects logged in Singapore (11 verified sightings), 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.
