Acorn Ants

Tiny peaceful ants- Beginner


Acorn ants are probably the cutest species of ant you will come across. These tiny colonies grow to 200-300 workers and quite literally fit into an acorn sitting peacefully in the ground litter of forest floors.


Being so small their colonies go unnoticed to anyone walker overhead. Unifasciatus are found across Europe in very different temperatures. They are durable and resilient to heat and cold making them great for beginners.


With this in mind we feel the day and night routine is quite essential for acorn ants, they are not protected by stable climates deep in the earth and their behaviour and cycles can be dependent on the warm/cool cycles.


Acorn ants are extremely peaceful, the avoid conflict with other ants and are not usually pestered by most other species too. For that reason they can be compatible with other species in bigger setups and live in the same enclosure on the surface with their neighbours of another species.


With the exception of sugars which they collect from aphids and plants the do not really compete with other ants for food. Silently foraging on the forest floor they will prey on small protein sources like spring tails and dipterans.


Although they are considered monogyne they have been known to tolerate another queen, especially where their nest is divided over 2 acorns for example. Other species of Acorn ants however such as Temnothorax Angustulus are far more arboreal in forraging and are polygyne making larger colonies overall.


This species is best suited to a small acorn (ideally hollowed) and placed in an outworld to mimic their natural environment. Ideally a room which heats and cools in an area with indirect light (like the shadow light under an oak tree is)
