Grasshoppers are herbivores , delicacies of these insects include cotton, clover, wheat, alfalfa, barley, corn, rye, oats and many other agricultural crops.A grasshopper has an open circulatory system which means the blood flows into open spaces or sinuses. An open circulatory system is one where blood bathes the internal organs directly. Most of the body fluid (haemolymph) fills body cavities and appendages.This haemolymph circulates nutrients through the body and carries metabolic wastes to the malphighian tubes to be excreted. Because it does not carry oxygen, grasshopper “blood” is green. The digestive system of insects includes a foregut ,a midgut and a hindgut. In some countries, grasshoppers are eaten as a good source of protein.
In Mexico, for example, grasshoppers are considered by their high content of protein, minerals and vitamins. They are abundant in Mexican food and street markets, especially in the central regions.Do you know what are the greediest insects ?
Locusts are a type of grasshopper. They live in dry, warm places. if locusts find a field of crops, they swoop down in large swarms and begin to feast. The whole field can be gone in less than an hour.
