Trachymyrmex Septentrionalis Care Sheet

Species information:

Queen: 5-6mm
Drone: 5mm
Worker: 3-4.5mm
Fungus Garden: Pinhead-Softball


In the wild Trachymyrmex Septentrionalis tends to nest in well-drained sandy soil. So a formicarium that resembles which is your best bet. I find that a great formicarium for Trachymyrmex Septentrionalis consists of only a few items:         Acrylic/glass boxes, tubing, plaster, sand, and metal mesh/cotton.

A setup such as the one above is a simple setup that proves to be both affordable and an ideal formicarium when it comes to keeping Trachymyrmex Septentrionalis.

Temperature And Humidity 

Having the correct temperature and humidity for your ants and their fungus is crucial. It spells life or deaf for the colony. Although Trachymyrmex Septentrionalis is much more forgiving when it comes to temperature and humidity, it is still important to make sure their temperature and humidity are as perfect as can be. I find that as long as there’s water droplets accumulating on the glass/acrylic, then the humidity and temperature is in most cases ideal. These ants do fine at room temperature 20-22 °C (68-72 °F) but a few degrees in either direction would not hurt. As long as it doesn’t get below 16° (60°F )or above 27°  (80°) you are in the safe zone.

Feeding And Watering

As you may know, Trachymyrmex Septentrionalis gather insect frass and detritus as part of their fungus’s main diet. But there’s so much more food items that they like to use in their fungus gardens: 

insect frass, detritus, leaves, grass, flowers, oats, green apples, lettuce, grapes and in some cases insect parts

When it comes to watering, I like to make sure that the plaster is almost at full capacity. This ensures long-lasting humidity, healthy fungus, and healthy brood.

Fun Facts

Trachymyrmex Septentrionalis have the ability to play dead. They assume death curl position when attacked or approached by a predator or enemy. It’s been seen with both queens and workers, drones tend to either run or fly away at the sight of danger. 

Trachymyrmex Septentrionalis have the ability to stridulate at a frequency most humans can hear. They do this a lot when in danger. If a worker from one nest is attached by a worker from another, she rubs two parts of her abdomen together to make a sound known as stridulation.
