Pheidologeton diversus
In 3 days ~10% in a week ~30%
Carebara diversa, commonly known as the East Indian harvesting ant, is a species of marauder ant widely distributed throughout Asia. Carebara diversa is a eusocial insect and individuals have continuous allometric variation in size and morphology to facilitate task allocation and partitioning of work. Minor workers are between 1.3 and 2.5 mm in length, but major workers are much larger. Between the smallest minor and largest major workers there are many intermediate forms. The largest workers can have heads approximately 12 times as large as those of their smallest counterparts. The dry weight of a large major worker can be approximately 550 times as heavy of that of its smallest counterpart. These size-related morphological differences correspond with their division of labor. For example, small, young, minor workers specialize in caring for the larvae but extend their activities as they grow older.
Minor workers have yellowish brown to reddish brown bodies. Their mandibles each have five "teeth" and their antennal scapes are short and do not exceed the posterior margin of the head. Minor workers have rectangular heads with weakly convex posterior margins in full... Wikipedia →

Rare
Under 5% of wildlife watchers report an Asian Marauder Ant sighting in Singapore on a given day, based on 55 verified sightings from GBIF citizen-science data. It is the 344th 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 30%, if each day is a fresh chance.
January, March and October–November
In those months about 10% of wildlife watchers report an Asian Marauder Ant in Singapore on a given day, against under 5% in February, April–September and December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Asian Marauder Ant sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 9
Of the 9 cities where we can rate Asian Marauder Ant sightings, Singapore ranks 6th at under 5%. The best odds are in Taichung (Taiwan, about 10%), Manila (Philippines, about 10%) and Kuala Lumpur (Malaysia, about 10%).
Same family: Formicidae
The closest relatives of the Asian Marauder Ant 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 Asian Marauder Ant is recorded against all the insects logged in Singapore (55 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.
