Polyrhacis Dives (cheapest UK supplier)
Country of Origin
They are believed to originate from Southeast Asia but are also common in Australasia e.g Papua New Guinea
Easy, Skilled, Specialist
They are a fairly easy species to keep, but require a temperature of at least 24 degrees Celsius and good escape prevention. I have found baby powder and PTFE work well.
Can number up to a few thousand individuals
Expected life expectancy
Ranges from rainforests to grasslands
The most noted behaviour of Polyrachis Dives is the ability to weave nests using moss, twigs, grass etc using silk produced from their larvae. These nests unlike the genus Oecophylla are weaved on the ground. They are also a fairly aggressive species willing to defend their territory. They are very clean ants that are constantly cleaning each other inside the nest.
Polyrachis Dives much like most other ants have 4 stages of development. Egg, larvae, pupae then worker. Workers that first emerge from pupae are usually a light grey to brown and turn darker after a few days. The larvae stage is when they produce silk and are used for the construction of nests.
These are aggressive ants that are very willing to defend their territory. When threatened, they opened their jaws wide and bend their abdomens underneath them, preparing to spray formic acid, and wave their antennae high in the air. Though while threatened at the nest entrance they flick their abdomens against the ground with wide open jaws to create a small click noise to frighten off predators or attacking colonies.
Possess the ability to spray formic acid, this isn’t a cause for concern for a human or animals.
I have found they feed fine on crickets and mealworms but reject waxworms. They like to have a little humidity, always staying close to areas with condensation. And that it is important to give a temperature gradient. As I see them moving where they want to be all the time. I’ve also got my colony completely used to light and have a torch shining on them which they are completely unfazed by.
