Camponotus ants do not have a metapleural gland [106] and Camponotus maculatus as well as C. floridanus workers have been found to amputate the affected legs of nestmates when the femur is injured. A femur injury carries a greater risk of infection unlike a tibia injury.
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Charles Darwin wrote of the interaction between size and complexity of invertebrate brains: . It is certain that there may be extraordinary activity with an extremely small absolute mass of nervous matter; thus the wonderfully diversified instincts, mental powers, and affections of ants are notorious, yet their cerebral ganglia are not so large as the quarter of a small pin's head.

We’re not quite as intriguing as we think we are.
Not all animals have neurons; Trichoplax and sponges lack nerve cells altogether. Neurons may be packed to form structures such as the brain of vertebrates or the neural ganglions of insects. The number of neurons and their relative abundance in different parts of the brain is a determinant of neural function and, consequently, of behavior.
Most male ants are not known to have metapleural glands. It is believed that they benefit from the shared secretions of ant workers and do not need any themselves. [7] Additionally, slave-making ants do not have metapleural glands, though the slave species they use do and it is these ants that groom the slavemakers and their brood. [7]
The latest curiosity is a video that surfaced on YouTube showing a phone placed on the ground where a group of ants is moving randomly. When the phone receives an incoming call, the ants start ...
