Arthropods
Arthropods make up the largest phylum of animals in theanimal kingdom. Arthropod means “jointed foot”. Allarthropods have jointed appendages. Arthropods alsohave segmented bodies and an external covering called an exoskeleton.

Insects
Insects are one type of arthropod. Insects have threebody regions: a head, a thorax, and an abdomen.
All insects also have six legs, one or two pairs of wings,one pair of antennae, and a pair of compound eyes.

Parts Of The Head
Use the diagram below to identify the parts of the headon your grasshopper.
The grasshopper has 5 eyes, two compound eyes andthree simple eyes. The antenna are sensory organs located on the head.

Mouth Parts
Use the diagram below to identify the mouth parts on your grasshopper. As you identify each part, try and remove it with your tweezers.

The labrum is used to hold food. The mandibles are teethused to chew food. The maxilla are used to chew and taste food. The labium is used to hold food while it isbeing chewed. Now use the diagram below to locate theexternal structures on your grasshopper.

A grasshopper’s eardrum, or tympanum, is located belowthe second pair of wings on each side of the thorax.Locate the tympanum on your grasshopper using thepicture below. The tympanum is used for hearing.

Like all insects, grasshoppers have six legs. The front pairare used for walking, climbing, and holding food. The middle legs are also used for walking and climbing. Thehind legs are used for jumping.
