Polyrhachis dives

The Polyrhachis dives is a striking species of Asian ant known for its cooperative behavior and its ability to build nests with silk produced by its own larvae. It belongs to the genus Polyrhachis, a very diverse group of arboreal ants characterized by their spiny body structures and their lifestyle in trees and vegetation.

This species is especially valued by myrmecology enthusiasts due to its advanced social behavior, intense activity, and the fascinating way it builds nests using plant fibers and larval silk.

Characteristics of Polyrhachis dives

Origin: Southeast Asia (China, Vietnam, Laos, and nearby regions)

Colony type: generally polygynous (multiple queens)

Coloration: glossy black with metallic reflections

Characteristic Morphology

• body covered by a very shiny chitin

• presence of characteristic dorsal spines of the genus Polyrhachis

• slender body adapted to arboreal life

• long legs that facilitate movement on branches and vegetation

Workers typically measure between 6 and 8 mm, while queens can reach slightly larger sizes.

These adaptations are directly related to their arboreal lifestyle, where mobility and nest defense are fundamental.

Natural Habitat

In nature, Polyrhachis dives lives primarily in tropical and subtropical forests, where it builds nests in trees, shrubs, or dense vegetation.

Their colonies are usually found in:

• tree branches

• dense bushes

• humid forest areas

• tropical vegetation

Unlike many other ants, this species does not live underground; instead, it builds elevated nests using silk produced by larvae. Workers hold the larvae as they release silk, which they use to bind leaves and plant fibers.

The result is a compact and resistant structure, similar to small woven sacs or shelters.

Behavior

Polyrhachis dives exhibit extremely interesting behavior to observe in captivity.

Among their most characteristic behaviors are:

• nest construction using larval silk

• cooperation among numerous workers during construction

• high activity in the foraging area

• well-organized defensive behavior

Colonies can grow rapidly and have several queens, which favors relatively quick expansion.

Their cooperative social behavior makes observing the nest construction and worker activity particularly fascinating.

Diet

Polyrhachis dives is primarily omnivorous with a nectivorous tendency.

Recommended diet:

• sugar water or sugary solutions

• diluted honey

• small insects (flies, crickets, small cockroaches)

• occasionally ripe fruits

Sources of sugars are a fundamental part of their diet, as they provide energy for the colony's intense activity.

Insects provide the necessary protein for larval development.

Ant Farm Recommendation

Due to its arboreal nature, this species adapts better to rearing systems that allow vertical structures or ample foraging areas.

It is advisable to provide:

• areas with branches or structures where they can fix their nest

• good ventilation

• moderate humidity

Modular systems allow for perfect observation of colony activity, while a spacious foraging area facilitates natural exploration and food gathering behavior.

AntMaster foraging areas offer the ideal space for these ants to develop their activity and build structures similar to their natural nests.
