Advantages and disadvantages of the species Monomorium latastei

Advantages:

This rare Monomorium species from Chile differs significantly from its relatives: It is non-invasive, grows slowly, and remains easily controllable. Its polymorphism with true majors (soldiers) makes it particularly exciting. Workers are very aggressive but have a sting harmless to humans. Observations suggest possible parthenogenesis in larger workers – though not yet scientifically confirmed.

Disadvantages:

The development from egg to imago takes a comparatively long time, about 3 months. The species is very aggressive towards disturbances and requires escape-proof formicariums. Due to its rarity and peculiarities, it is more suitable for experienced keepers.

Keeping

Monomorium latastei can be kept well under stable conditions but is not suitable for beginners.
In the founding phase, a test tube nest with a small arena can be used. As the colony grows, a well-ventilated, humidity-regulable nest with modular expansion options is recommended. Secure sealing is important due to the species' defensiveness.

Feeding

Very protein-loving!
Insects (e.g., flies, cockroaches, crickets) should be offered every 2–3 days.
