Trachymyrmex septentrionalis

From Ant Keeping Wiki

Like most fungus-growing ants, the distribution of T. septentrionalis is locally patchy. In part, this may be a consequence of the distribution of suitable soils. In the northern part of its range, T. septentrionalis occurs exclusively on pure sand soils in open habitats and open woodlands of the Pine Barrens. In the southern US, T. septentrionalis is abundant in a wide variety of similar oak and pine dominated habitat types, all characterized by very sandy soils and light (if any) shade. It has also occasionally been found nesting in sandy clay soils in well-developed forests with considerable shade, particularly in the southern part of its range.



Queen Ant
  • Nuptial Flight Time : May-July depending on region
  • Founding Type : Semi-Claustral
  • *gynous : Polygynous
  • Brood Boostable : Yes
  • Hibernation : Depends on region, if there's temperature under 50 degrees F, they will
  • Feeding Requirements : As often as you want fungus growth
  • Nanitics Appear After : 5-6 weeks, sometimes sooner.
  • Founding Stage Notes: Incredibly hard to found. Need a fungus pellet to be successful or collect some from a wild colony.



Every ant, even from same species may be temperamental to certain foods. Trial and error is best way to figure out she will eat. Compiled below is a list of likes and dislikes for this particular species.


(diet only consists of Leucoagaricus gongylophorus fungus, but likes various substrate to use as fertilizer)

  • Honey
  • Nectar
  • Rabbit feces
  • Caterpillar frass
  • Flower pollen
  • Oatmeal
  • Freeze dried Rose petals
  • Freeze dried strawberry slices
  • Fresh grape leaves
  • Various other leaves
  • Juice consisting of sugar, carbs, and fats
  • LOVES Cornflakes
  • Apple Jacks
  • Shaved almonds


  • ?
