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 ...
These medium-sized grasshopper are characterized by a significant sexual dimorphism. Males have developed functional wings (oft 20–27.3 millimetres (0.79–1.07 in) [ 3 ] covering the abdomen, while females have rudimentary wings (of 12.3–20.1 millimetres (0.48–0.79 in)), [ 3 ] shorter than abdomen and unfit for flight ( brachyptery ).
