Ants don’t actually “drink” — they use a highly specialized feeding system. In this article, discover how ant mouthparts work, including the glossa, labium, maxillae and mandibles, and how ants absorb liquid food, filter particles and transport nutrients through their unique two-stomach system. Learn how feeding, digestion and trophallaxis function inside an ant colony — and what this means for antkeeping and proper nutrition.
Ants and their symbiotic relationships are among the most fascinating examples of cooperation and conflict in nature. From mutualism to parasitism, ants interact with a wide range of species—including aphids, fungi, bacteria, and even other ants—forming complex ecological networks.
In mutualistic relationships, ants protect aphids in exchange for honeydew, defend acacia trees that provide food and shelter, and cultivate fungus as a primary food source. Some species, such as Camponotus, even rely on internal bacteria to produce essential nutrients, highlighting the depth of ant symbiosis.
However, not all interactions are beneficial. Many organisms exploit ants through mimicry and deception. Butterfly larvae, beetles, and spiders infiltrate ant colonies to steal food or prey on brood, blurring the line between mutualism and parasitism.
Ants themselves also engage in social parasitism. Slave-making ants raid other colonies to capture workers, while parasitic queens invade nests, eliminate the resident queen, and take control of the colony. In some cases, such as superparasitism, multiple parasitic layers exist within the same system.
One of the most extreme examples of parasitism is the Cordyceps fungus, which infects ants and manipulates their behavior to spread its spores. This phenomenon demonstrates how evolution can produce highly specialized and dramatic survival strategies.
Overall, ant symbiosis is not limited to simple categories like mutualism or parasitism. Instead, it forms a dynamic spectrum of interactions that shape ecosystems and reveal the extraordinary adaptability of ants.
What happens when an ant develops the wrong way? In some colonies, these unusual individuals—often called “monster ants”—emerge with oversized features and strange proportions. But rather than being a failure, these biological accidents can become unexpected advantages for the colony.

La vida en la ciudad no sólo estresa a los humanos: ¡también cambia el comportamiento de las hormigas! 🐜
Un nuevo estudio de la Universidad Libre de Berlín demuestra que las hormigas urbanas son mucho menos exigentes con la comida que sus homólogas rurales, y beben con gusto soluciones azucaradas débiles que las hormigas del campo ignorarían. Los investigadores creen que este sorprendente comportamiento puede deberse al estrés urbano, como el calor, la contaminación y la escasez de alimentos.
¿Podrían convertirse las hormigas en bioindicadores de la salud de los ecosistemas? Descubre cómo las diminutas hormigas urbanas revelan grandes verdades sobre la vida en la ciudad.
Estructuras de nidos, exoesqueletos y partes del cuerpo explicadas
Reinas, obreras, machos y la estructura social de las colonias de hormigas
Ciclo de vida, alimentación y relaciones ecológicas de las hormigas
Todo lo que necesitas saber sobre la Paraponera clavata, la “hormiga bala”.”
(Pista: no es quien crees) ¿Dirige la hormiga reina la colonia? Las colonias de hormigas no tienen un líder único como imaginamos los humanos: la reina no manda ni controla a sus obreras. En su lugar, las sociedades de hormigas funcionan a través de la inteligencia distribuida, donde el comportamiento colectivo surge de simples acciones individuales y de la comunicación química. Este sistema descentralizado permite a las colonias tomar decisiones complejas, adaptarse a los retos y funcionar eficazmente sin una estructura jerárquica de liderazgo, redefiniendo lo que significa “organización” en la naturaleza.
