Monomorium floricola

Name: Monomorium floricola
Origin: Tropical and subtropical worldwide (originally presumably Africa/Asia, now globally distributed)
Queen: approx. 4 – 5 mm
Workers: approx. 1.5 – 2 mm
Nutrition: Carbohydrates (e.g., honey, sugar water), proteins (insects like fruit flies, small cockroaches, crushed crickets)
Humidity:
• Arena: 50 – 70 %
• Nest: 60 – 80 %
Temperature:
• Arena: 24 – 30 °C
• Nest: 24 – 28 °C
Hibernation: No
Nest type: Small 3D nests, acrylic nests with humidity chambers, or Ytong with fine structure are very suitable – absolutely escape-proof!

Colony size: several thousand to over 10,000 workers possible

Advantages and disadvantages of the species Monomorium floricola

Advantages:

Monomorium floricola is a very small, extremely active species with rapid colony development. It is excellent for compact setups and shows interesting social behavior. Due to its size, it can also be kept in smaller setups with a high number of workers.

Disadvantages:

Due to its extremely small size, it is very prone to escape. Even the smallest cracks are enough for them to escape – perfect sealing and escape prevention (e.g., PTFE) are absolutely necessary. Additionally, the colony can grow very quickly under optimal conditions.

Keeping

Monomorium floricola is a tropical species and requires constant warmth as well as increased humidity.

During the founding phase, a small test tube with an arena is suitable. Very good escape prevention is important, as even young colonies can escape through the smallest gaps.

Later, a moist, well-ventilated 3D or acrylic nest with an arena of at least 20x20 cm is recommended. Due to their strong growth, expansion space should be planned early.

This species is active day and night and constantly foraging – ideal for keepers who want to observe constant activity in the formicarium.

Feeding

Very food-active – especially at warm temperatures.

• Offer proteins such as fruit flies, small cockroaches, or crushed crickets every 2–3 days

• Provide carbohydrates such as sugar water or honey continuously – change regularly to prevent fermentation

At higher temperatures, the food requirement increases significantly. Cleanliness is particularly important, as food residues can quickly mold in a humid climate.
