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 ...
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]

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 ...
