Orthoptera is a larger order in the insect class, including common insects such as locusts, crickets, katydids, and mole crickets.

Large or medium-sized, with sucking and chewing mouthparts.

The forewings are long and narrow and slightly hardened, and the hind wings are membranous. Some species have short wings or even no wings. Some species have extremely strong flying capabilities and can fly long distances.

The hind feet are strong and suitable for jumping.

Acrididae: East Asian migratory locust, clouded locust; Acrididae: Chinese rice locust, Japanese yellow-ridged locust; Molecidae: single-spined mole cricket, Oriental mole cricket.

Thysanoptera, commonly known as thrips, have tiny bodies.

Generally yellowish brown or black.

Eyes are well developed.

The tentacles are long and the mouthparts are rasp-type.

The wings are membranous, with dense and long tassel-like hairs on the wing edges.

Thripidae: rice thrips, tobacco thrips, greenhouse thrips; Thripidae: rice thrips, wheat thrips.

Homoptera (Homoptera) Cicadas, leafhoppers, planthoppers, psyllids, whiteflies, aphids and scale insects all belong to this order.

They are mostly small insects with piercing-sucking mouthparts. The base of the insect is inserted behind the ventral surface of the head, seemingly emerging from between the bases of the forelegs.

Both the front and rear wings of winged species are membranous, covering the back of the body in a roof-like shape when resting. Many species of female insects are wingless, and scale insects and aphids often have wingless types. Leafhoppers and aphids can also spread plant virus diseases.

Planthopper; Aphididae: cotton aphid, wheat aphid, wheat aphid, green peach aphid, sorghum aphid, radish aphid; Aphididae: cottony scales; Scutellariae: mulberry shield scales, sagittal shield scales

, pear round scales; Cerechidae: ash scales, red wax scales, Korean ball scales; Hemiptera (Hemiptera) is commonly known as "bugs" or "stink bugs"; most of the bodies are wide and slightly flat, with the base half of the forewings leathery and the ends

Half of it is membranous, called hemi-elytra; it has piercing-sucking mouthparts, and its nymph has odor glands on its abdomen, so it is also known as "bed bug" and "fart bug".

Stycinidae: Pear stink bug, Banana stink bug; Chrysanthemumidae: stink bug, Microchrysalis; Trinidae: stink bug, Oryza stink bug; Trinidae: brown stink bug, black stink bug, rice bug

Green bug.

Lygustaidae: Green Lygus, Medicago lucerta, Lygus mesocarpa; Neuroptera, often called "flying flies"; mouth type under the head, chewing mouthparts.

It preys on carnivorous beneficial insects such as aphids and butterfly moth larvae.

Lacewingidae: Great Lacewing, Lepidoptera sinensis, Lacewing sinensis; Lepidoptera (Lepidoptera), the second largest order in the class Insecta.

The biggest feature is that the wings are covered with small scales, and the adults are called moths or butterflies.

Siphon-type mouthparts, forming a long and rollable beak; there are about 140,000 known species, of which more than 90% are moths and less than 10% are butterflies.

Similarities and Differences between Moths and Butterflies: The ends of butterfly antennae are enlarged, while those of moths are linear or feathery; when butterflies are resting, their wings are folded and stand on their backs, while when moths are resting, their wings are placed flat on both sides of the body or contracted into

Roof-shaped; butterflies are mostly active during the day, while moths are mostly active at night and usually have strong phototaxis.
