Physical Description
     The grasshopper's body is divided into three sections: the head region, the thorax region, and the abdomen region. The head has a pair of antennae, simple eyes, compound eyes, mouth parts containing two palps. The thorax region has one pair of legs used for walking. The abdomen region  consists of the wings, tympanum, spiracles, and two pairs of legs. The large back legs are used for jumping while the small front legs are used for walking. If the grasshopper is a male it will have a round, blunt end designed for transfer of sperm, while a female will have four prongs on her end, called an ovipositor, used for egg-laying. The grasshopper has a hard outer shell (called an exoskeleton) made of chitin. The chitin helps to conserve moisture in the grasshopper and the exoskeleton helps protect against injury.

 

Roles of Features
     Antennae- detect odour and touch
     Simple eyes- sense changes in light brightness
     Compound eyes- sense movement and crude images
     Mouth parts- designed for chewing
     Palps- used for tasting
     Wings- thin but rigid and veined
     Tympanum- a round membrane designed for the grasshopper to detect sound waves
     Spiracles- tiny holes that allows air to enter the trachea

Senses
     The five senses are sight, hearing, taste, touch, and scent. The grasshopper uses its two pair of eyes (the simple and compound) to see, the tympanum to hear sounds, palps to taste, the antennae for feeling and smelling.

Locomotion
     The grasshopper has many forms of locomotion. They include walking, running, crawling, jumping, and flying.

Survival
     The grasshopper has a hard outer shell called an exoskeleton made of chitin, to protect it. It also preserves moisture.
