Description

Monomorium chilense is a small, fast-developing ant species native to South America. Workers measure 2–3 mm, and queens about 5–6 mm. They are light to reddish-brown, highly active, and efficient foragers. Colonies grow quickly with warmth and protein-rich diets. Though non-aggressive, they are excellent escape artists and require secure, compact nests. Ideal for keepers seeking a small, adaptable, and low-maintenance species.

Monomorium chilense 


Colony Type:

Monogynous (single queen colonies are standard)

Colony Size:

Up to 5,000–7,000 workers in mature colonies

Development Speed:

Fast to Medium
(Growth is rapid in warm temperatures and with frequent protein feeding.)


Size:

  • Queen: 5–6 mm

  • Workers: 2–3 mm


Coloration:

Monomorium chilense workers are generally light to reddish brown, with a subtle sheen across the exoskeleton. Their small size and uniform coloration make them discreet but efficient foragers. Queens are slightly darker and more robust, with proportionally larger gasters.


Diet:

  • Insects: fruit flies, small mealworms, cut-up crickets

  • Sugars: 3:1 or 4:1 sugar/honey to water syrup

  • Fruits: apple, banana, pear (in small quantities)

  • Protein sources: protein jelly, cooked unsalted egg white or chicken

  • Supplement: tiny pieces of fish flakes or crushed dried insects

Tip: Due to their small size, offer finely chopped or soft-bodied food.


Environmental Conditions

  • Humidity:

    • Arena: 40–60%

    • Nest: 50–70%

  • Temperature:

    • Arena: 24–30 °C

    • Nest: 23–27 °C


Adaptations:

This species is adapted to dry and temperate climates and thrives with moderate warmth and humidity. Despite its tolerance for dry conditions, a lightly hydrated nest area is crucial for brood development.


Unique Traits of Monomorium chilense:

  • M. chilense is a tiny, agile species known for its highly efficient foraging and flexibility in diet.

  • Colonies are non-aggressive and usually shy when disturbed, retreating rather than fighting.

  • Due to their small size, they are excellent escape artists — tight-sealing setups are essential.


Nesting Recommendations:

  • Mini acrylic or 3D-printed nests with narrow chambers

  • Test tube setups (ideal for founding stages)

  • Plaster or YTONG nests with moisture gradient

  • Avoid large open nests; they prefer compact, low-clearance environments.


Summary:

Monomorium chilense is a small, fast-growing ant species suited for keepers who enjoy observing subtle behaviors and efficient colony dynamics. While visually modest, their adaptability, active foraging, and ease of care make them a great choice for both beginners and experienced keepers looking for a compact species. With proper humidity, secure housing, and consistent feeding, colonies will thrive and grow steadil
