    • Species Info

      Formica incerta are brownish/black ants from the fields of the midwest and northeast. They are medium sized, energetic, and fairly beginner-level ants to keep.


      Diet is very general - Formica incerta love sugars, like honey or sugarwater, and proteins such as crickets, fruit flies, and mealworms. Fruit flies appear to be a favorite.


      Colonies benefit from a heat source. A good temperature for this species is ~80 degrees. It may be ideal to provide a heating gradient in the nest, but this species can usually handle heat well. 


      This species requires a diapause period, which should last 3-4 months ideally. During this time, the ants need to be cooled down to a low temperature, with around 40 degrees fahrenheit being ideal. You can achieve diapause by placing the ants in a controlled cooling unit, such as a wine cooler, mini fridge, or regular fridge if temperatures are safe. If you cannot use any of these, a non-heated room which stays above freezing could work. 


      Formica incerta can be polygynous. This means multiple queens can cooperate in a single colony. Having multiple queens can speed up the growth of the colony, and increase the max colony size. 


      Brood development takes anywhere from 5-8 weeks, usually around 6-7 weeks total. Colonies can get into the dozens first year, typically hitting the hundreds in their second or 3rd year. Rarely do colonies exceed 1000-2000 individuals.


      Queen Size: 8-11mm

      Worker Size: 5-8mm
