The word Hexapoda itself comes from the Greek word meaning "6 feet," therefore all members of Hexapoda subfilum have three pairs of legs / 6 pieces.
This is what makes Hexapoda very different from other arthropod groups that have more than 6 legs.
Arthropoda is an animal that has a body of segmented, framed exoskeleton outside and with a relatively symmetrical shape. This primitive species of insect has legs on every part of its body.
Insecta class or insect has 6 legs attached to the chest has a body consisting of three parts, namely the head, chest or thorax and the abdomen or abdomen.
At the head of the insect, there will be a pair of eyes in the form of compound eyes, a pair of tactile and 3 pairs of mouth.
This insect has several types of mouth types, namely the type of mouth bite/cockroach, the type of mouth bite and the licker on the bee, the type of sucking mouth in butterflies and the type of piercing in mosquitoes. Types of respiratory equipment possessed by insects in the form of trachea and excretion tool in the form of Malpighi body.
The reproduction of insects takes place in a sexual manner with the result of an egg marriage and gradually transforms into an imago.
During the life cycle of the insect undergoes a change of form called the metamorphosis, ie by doing the exfoliation of the skin commonly called ecdysis.
There are two kinds of metamorphosis, ie imperfect metamorphosis or hemimetabolous and perfect metamorphosis or holometabola.
1. Perfect Metamorphosis
perfect morphosis is a metamorphosis that occurs with the developmental stage begins with the egg - larva - pupa - imago. Examples of species with perfect metamorphosis are butterflies and flies.
2. Imperfect Metamorphosis
Imperfect metamorphosis is a metamorphosis that occurs when one of the developmental stages does not take place. Examples of species with imperfect morphoses are crickets, cockroaches, and dragonflies.
Classification of Hexapoda
Order of the Protura
1. Protura is a small whitish Hexapoda with a length of 0.6 - 1.5 mm.
2. Its head is somewhat of a conical shape and has neither eyes nor antenna.
3. The parts of the mouth do not bite but are used to gnaw the food particles which are then mixed with saliva and then sucked into the mouth.
4. The first limb pair functions as sensory and is located in a raised position like an antenna.
5. There is a stile on the first three sections of the abdomen.
6. After hatching from the egg, the Protura abdomen consists of 9 In every 3 subsequent shifts the sections are added to the anterior portion of the tip/telson, so the adult abdomen has 12 segments.
7. These hexapods have habitats in moist soil/ground flowers, live on leaf fungi, at the bottom of the bark and also on deep logs.
8. Type of this type of hexapod food is a decaying organic material and also spores-spores mushrooms.
9. The family of Protura class is Eosentomidae and Protentomidae.
Order of Collembola
1. Another name collembola is a springtail derived from a branching structure/formula that rotates this small hexapode through the air.
2. This animal will make a jump when mating activity.
3. The mouthpiece of the Collembola is rather long and is hidden in the head.
4. Type of food Collembola, in general, is the plants, in addition, there are also omnivorous, and a liquid eater with a mouth shaped like a stilet.
5. This Hexapoda has an emblem like a tube called Collofor which functions in water retrieval.
6. The size of the insects of this spring is very small that is 0.25 - 6 mm.
7. Habitat Collembola in a hidden place like in the ground, in the ruins of leaves or bark, and on the rotting wood and on the fungus.
8. Most ground-dwelling springs feed on decaying vegetation, fungi, and bacteria, while other types of spikes are eating arthropod feces, pollen, algae and other materials.
9. Some types of springtails can sometimes cause damage to gardens and greenhouses.
10. Some families of Collembola or springtails are Entomobryidae, Isotomidae, Hypogastruridae, and Sminthuridae.
Order Diplura
1. The diploma looks like a silver insect and a brittle tail, but this diplomatic order does not have a median tail filament and has only two tail filaments.
2. The body of the diplura is usually not covered with scales and has no compound eyes or single eyes.
3. There are still on the segments of the abdomen 1 - 7.
4. The length of the hexapods is less than 7 mm.
5. The habitat of diplura is in places that are moist in the soil, at the bottom of bark, rocks, caves and other humid places.
6. Some families are often found that Campodeidae, Anajapygidae, and Japygidae.
