Myrmica incompleta

From Ant Keeping Wiki

This ant inhabits deciduous forests where it forms large colonies with many queens (polygynous) and consisting of numerous nests (polydomous) in moist soil and in mounds of moss. It is host for the xenobiotic ant Formicoxenus provancheri.



Queen Ant
  • Nuptial Flight Time : Use: ant-mating-chartable to mate whithin nests
  • Colony Founding Semi-claustral
  • *gynous : Highly polygynous. Although most likely secondary-polygyny.
  • Brood Boostable: 
  • Hibernation : 
  • Feeding Requirements :
  • Nanitics Appear After :










  • Difficulty : Easy
  • Typical Colony Size :
  • Polymorphic : Yes
  • Ant Length : Workers: 3.5-6mm, Queen: 6.5-7mm Males: 5-6mm
  • Temperament :  Workers: Mildly aggressive or timid. Will swarm if nest is disturbed (vertebrates). Queen: Timid 
  • Suggested Feeding Schedule :  
  • Hazards : Capable of stinging, initiated after biting.
  • Colony Growth Rate :
  • Egg To Worker :
  • Circadian Activity :
  • Recommended Temperature :
  • Recommended Humidity : Very humid
  • Heating Pad Required :
  • Can Climb Smooth Surfaces : Yes
  • When To Expand :
  • When Do Soldiers and Reproductives Appear Polymorphism is evident in the first batches of brood
  • Invasive/Pest : No
  • Farmers : No
  • Native Location :
  • Natural Habitat : Woodlands, forests (decideous, temperate, boreal) , wet meadows in open areas, wetlands commonly nests under various objects including wood (both rotting and alive), rocks and galleries inside wood. Will construct tunnels and seals of soil woven with grass and other vegetative debris.  This species is almost exclusively found in moist environments.
  • Preferred Nesting Medium : 
  • Scientific Information:


  • React very negatively to being collected from the wild
  • Workers are prone to dessication, require at least a source of water
  • Workers construct various structures as mentioned above
  • Can be fed inside a test tube
  • This species is highly variable in colour for both the queen and workers. Ranges from bicoloured black/darkred-orange/red/darkred, to uniformally dark red. 
  • 4.5-5mm workers comprise most of the foraging activity. Majors and minors often remain in the nest. Majors are noticably more aggressive while minors slightly more timid.
  • Easily confused with M.alaskensis
