The green katydid is a type of katydid. The katydids can be divided into five categories: the green katydid, the black katydid, the mountain green katydid, and the grass white katydid.

1. Green Grasshopper

Green katydids are mostly found in plains, farmlands, peanut fields, bean fields, corn fields, vegetable fields and other crop areas. Green katydids are characterized by being emerald green without any other colors. In the harsh winter, this large emerald green katydid can better show the beauty of nature and is particularly dazzling.

The black katydid is also called the iron katydid. It is blue-black in color, like the color of iron, so it is also called the iron katydid.

The appendages are 4-4-4, with pads on the 1-3 appendages, and the first appendage pad of the hind leg is divided into 2 blades. There are 6 spurs on the hind leg tibia, 2 on the back, 4 on the ventral, and the 2 in the middle are small. The hind leg femur is slightly longer than the tibia. It is omnivorous, but mainly preys on other insects. It can kill each other when hungry, and generally female insects eat more male insects.

Fried eggs or deep-fried katydids are also delicious dishes.

Why do katydids chirp only at night?

Katydid is a general name for some large insects in the order Orthoptera, class Insecta. They are large in stature and look like locusts. They have grass-green bodies and slender antennae. When the male insects rub their front wings against each other, they can make a clear and loud "kua-kua-kua" sound. They like to eat fruits, beans, etc. People raise them in small bamboo cages for viewing.

The male insect can make sounds. There is an arc-shaped sound file at the base of the left wing, which is 0.4 mm high, 0.15 mm wide, and 5.43 mm long. There is a transverse process every 0.029 mm. There is a 3.14 to 3.46 mm eardrum at the base of the right wing. The marginal veins are thickened, about 8 times thicker than the general wing veins, but the membrane is only 0.0286 mm thick. When making sounds, the two wings are erected obliquely and rubbed back and forth to make a loud sound to attract the opposite sex.
