The preference for energetic resources is positively associated with predatory activity in ants

Ecological Entomology, Volume 50, Issue 5, Page 921-932, October 2025.
We found that ants exhibit a stronger preference for foraging for carbohydrates and lipids (energetic nutrients) compared to amino acids. The increase in foraging for energetic nutrients compared to amino acids is positively correlated with foraging in larvae (insect predation). The nutrient preference between foraging for energetic nutrients and amino
