Daceton armigerum is a Neotropical species of arboreal ants, distributed throughout northern South America. D. armigerum combines several traits generally noted in some other arboreal ants i.e., populous colonies, large and/or polydomous nests, intra- and interspecific aggressiveness, trophobiosis, and capturing prey by spread-eagling them.
D. armigerum has a complex continuously polymorphic caste system, in which smaller workers nurse the brood and larger workers hunt, dismember prey items, and defend the nest. The workers have trap-jaw, hypertrophied mandibles that snap together, triggered by sensory hairs situated on the labrum and powering a killer bite. The polymorphism of the worker caste is dramatic, and the size-frequency unimodal (monophasic allometry); foraging workers, themselves highly polymorphic, are larger than those from inside the colony. Workers are so well adapted to arboreal life that when they fall from the forest canopy they are able to glide down onto the trunk of their host tree.
The species is distributed throughout northern South America and is known to occur in the terra firma and flooded forests of Bolivia... Wikipedia →

With luck
About 10% of wildlife watchers report a Daceton armigerum sighting in Tambopata National Reserve on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 86th most-seen of the 141 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Daceton armigerum in Tambopata National Reserve on a given day, against under 5% in February, April–June, August and November–December, the lowest months. That is one of Tambopata National Reserve's driest months, with about 90 mm of rain against 420 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Daceton armigerum sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate Daceton armigerum sightings, Tambopata National Reserve ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Manu National Park (Peru, about 10%).
Same family: Formicidae
The closest relatives of the Daceton armigerum that you can see in Tambopata National Reserve (family Formicidae, Ants) are Bullet Ant (about 40%), Ectatomma tuberculatum (about 20%) and Eciton rapax (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Daceton armigerum is recorded against all the insects logged in Tambopata National Reserve (6 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.
