Why do ants like building sand hills over their entrance?
Ants construct sand hills, or mounds, over their entrance for several reasons:
- Nest ventilation: The mound serves as a ventilation system for the ant colony, allowing air circulation and regulating temperature and humidity within the nest.
- Protection: The sand hill provides physical protection and acts as a barrier against predators or potential threats.
- Nest entrance marking: The mound, along with pheromones deposited by worker ants, marks the entrance to the nest and helps ants navigate back to the colony.
- Preventing flooding: By elevating the nest entrance, ants can prevent water from entering the nest during rain or flooding events.
Ants are adept at modifying their environment to meet the needs of the colony, and constructing sand hills over their entrances is one such adaptation.
