The queen is the reproductive member of the colony. Some ant species will only have one queen, while others will form polygynous colonies of multiple queens, such as Argentine ants Linepithema humile. [2] The workers are responsible for supporting the queen, maintenance, and foraging. Unlike queens and drones, workers are born wingless.
A neuron (green and white) in an insect brain (blue) Insect cognition describes the mental capacities and study of those capacities in insects. The field developed from comparative psychology where early studies focused more on animal behavior. [1] Researchers have examined insect cognition in bees, fruit flies, and wasps. [2] [3]
[18] [1] [19] [20] Some groups, such as the Leptanillinae and Martialinae, are suggested to have diversified from early primitive ants that were likely to have been predators underneath the surface of the soil. [13] [21] During the Cretaceous period, a few species of primitive ants ranged widely on the Laurasian supercontinent (the Northern ...
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.
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.

Ants do this when they lose track of their colony, and sometimes will keep walking until death Ants walk around in a never-ending circle known as an “ant death spiral” [Video] Skip to main content
