Advantages and disadvantages of Novomessor cockerelli

Advantages:

• Very fascinating desert species with striking large workers and majors.
  
• Interesting foraging behaviour – especially with grains and seeds.
  
• Robust against dryness and heat, therefore well suited to warm housing conditions.
  

Disadvantages:

• Needs a lot of space and a dry, warm environment.
  
• Can appear aggressive and is less suitable for absolute beginners.
  
• Slower growth compared to tropical species.
  

Care

Founding works best in a test tube nest with dry substrate. Later, a large sand-clay nest or an earth nest with sufficient roaming space should be provided. Since this species enjoys digging, a deep arena with substrate is recommended.

Feeding

Novomessor cockerelli is a harvester ant.

• Main food: seeds, grains, nuts (can be stored in the nest).
  
• Additionally, offer protein in the form of small insects 2–3 times per week.
