Aphaenogaster senilis– Southern European huntsman ant
Aphaenogaster senilis is an active and elegant ant species native to Southern Europe. This species is known for its long legs, slender build, and fast foraging behavior. Worker ants are almost constantly on the move and actively explore their surroundings in search of food, which makes this species particularly interesting to observe in a formicarium.
In the wild, Aphaenogaster senilis often lives in warm, dry areas such as open woodlands, scrublands, and Mediterranean landscapes. Colonies usually nest in the ground under stones or between plant roots. Worker bees are opportunistic hunters and collect both small insects and sweet fluids.
The colony grows at a steady to moderate pace and usually remains relatively manageable in size. Due to their distinct foraging behavior, interesting hunting technique, and good visibility in the arena, this species is highly suitable for enthusiasts who wish to keep an active ant species.

Power supply
Aphaenogaster senilis is an omnivorous ant species that requires both proteins and sugars for the healthy development of the colony.
Diet: insects such as redrunners, crickets, mealworms, buffalo worms, and dubia cockroaches.
Sugars: such as Byformica sunburst ant nectar, honeydew, sugar water and beetle jelly.
For good brood growth, it is important to regularly offer small insects as a protein source.
Care
Aphaenogaster senilis prefers a dry to slightly damp nest with a distinct moisture gradient. This allows the ants to choose the ideal location for their brood themselves.
In a formicarium, the workers are often active in the arena and respond quickly to food. This makes the species very fun to observe.
From how many workers to a nest: +- 40 workers
Recommended nest type:
3D nest, Ytong nest, Acrylic nest, plaster nest
Due to their active behavior and good visibility, Aphaenogaster senilis is an attractive species for both novice and more experienced ant keepers.
