What are the nine orders of the class Insecta?

Orthoptera, Tasseloptera, Homoptera, Hemiptera, Pulseptera, Lepidoptera, Diptera.

Hymenoptera Coleoptera.

Coleoptera Lepidoptera.

Odonata. Diptera.

Also called Heteroptera.

Orthoptera Praying Mantis.

Mayflies.

Common insects can be divided into Coleoptera, Lepidoptera, Diptera, Hymenoptera, Orthoptera, Broadptera, Dragonflies, etc. Insects belong to arthropods among invertebrates, and our common butterflies, bees, dragonflies, flies, and mosquitoes all belong to insects.

Insect legend. 1.Coleoptera, such as our common Scarab, Seven-Star Ladybug, and Feces Shell Lang all belong to the order Coleoptera.

2.Lepidoptera, mainly moths and butterflies, all kinds of butterflies and moths belong to the order Lepidoptera.

Butterfly. 3.Diptera, Diptera includes a wide range of mosquitoes, midges, gnats, flies, flies, etc.

Mosquito. 4.Hymenoptera, all kinds of ants and bees belong to the order Hymenoptera.

Bee. 5.Orthoptera, common insects such as mantis, crickets, mole crickets, locusts, etc., all belong to the order Straightptera.

Cricket. 6.Broadptera, Broadptera is a relatively small order, common species are Palearctic Lacewing, Oriental Megalodon, Chinese Spotted Fish Lacewing, etc.

Lacewings. 7.Dragonflies, dragonflies belong to the more primitive dragonflies in the insecta, and they are also smaller orders.

Dragonfly.

Class 37. 1. Coleoptera is the first order in the class of insects, commonly known as "beetles". There are more than 330,000 species, accounting for 40% of the total number of insects. More than 7,000 species have been recorded in China.

2. Lepidoptera is the second largest order in the class of insects after Coleoptera, and is named because of the large number of scales on the body and wings. It is mainly divided into moths and butterflies, and the common identification feature is the siphon mouthparts.

3. Diptera includes mosquitoes, midges, gnats, flies, flies, etc., and is the larger order of insects. Because the forewings of the adult worm are membranous, the hindwings degenerate into "balance rods". Diptera are divided into three suborders: long-horned, short-horned, and annular.

4. Hymenoptera includes a variety of ants and bees. Hymenopteran insects have obvious characteristics, including chewing and sucking mouthparts, and the connection of the front and rear wings is completed by wing hooks. This group is widely distributed, with more than 100,000 known species and an estimated at least 250,000 species.

5. Hemiptera, composed of two suborders, Heteroptera and Homoptera, have 133 families and more than 60,000 species. The heteroptera is the Tsubaki. It is one of the main groups in the class Insecta. The forewings of hemipteran insects cover the back of the body when at rest, and the hindwings are hidden underneath.

6. Orthoptera is a relatively common class of insects, including mantis, crickets, mole crickets, locusts, etc., with more than 20,000 species known in the world and widely distributed. The forewings of the adult are slightly hardened, called "over-the-top wings", and the hindwings are membranous.

7. Broadptera is a small group, with only two families, Lacewings and Lacewings. It is distributed worldwide, and about 300 species have been recorded. There are more than 40 species known in China, and the common species are Palearctic Lacewing, Oriental Megalodon, Chinese Spotted Frog and so on.

8. Dragonflies are a relatively primitive group in the class of insects, and they are also a smaller order. Dragonflies are divided into three suborders: the suborder Somiptera is collectively referred to as "dragonflies"; The suborder Homoptera is collectively referred to as "cocktails" and two species of mesoptera insects found in Japan and India.

In addition to the 7 orders mentioned above, there are 27 other orders, a total of 34 orders. There are many species and different morphologies of insects, but they have an exoskeleton and three pairs of legs as their common characteristics.

1. The class of insects is divided into 33 orders. Insecta is not only the largest class in the phylum Arthropoda, but also the largest class in the animal kingdom, and the number of individuals of the same species is also very staggering. It can be found in almost every corner of the world, and there are about 1 million known species of insects, but many species are still to be discovered.

2. There are about 1 million species of insects in the world, some people estimate that there are 2 million species, and about 10,000 new species are discovered every year. There are about 12,150,000 species in China.

3. There are many kinds of insects (about 80% of the number of species in the animal kingdom), with different habits and a wide range of distribution. Insects have a strong ability to fly, and their tiny bodies are easy to spread with air currents, so they can be found from the equator to the poles.

4. For example, butterflies have been found at 80°N, and mosquitoes have been found at 70°N; Insects have also been found in the Antarctic Circle. Hemiptera insects have been found in the mountains at an altitude of 5,029 meters above sea level, lepidopteran insects have been found in the mountains at an altitude of 488 meters, and several wingless subclass insects tend to live at higher altitudes. The upper limit of the distribution of insects is 6,800 meters above sea level.

There are also insects in hot springs and caves.
