Tettigonidae, with slender antennae, longer than the body and green or brown body color. Is it a herbivore or an omnivore? The female insect has an ovipositor at the end of her abdomen, which is the feature that distinguishes the male from the female. 1, its life history goes through three stages: egg, nymph and adult, and it belongs to an incomplete metamorphosis insect. 2. The larval stage of this purpose is called "nymph" because it is almost indistinguishable from adults in appearance. The larval stage of this purpose is called "nymph" because it is almost indistinguishable from adults in appearance.

3. The upper wing is flat and covers the back of the body, and the lower wing is membrane-shaped, so it will be folded under the upper wing and stretched when flying.

4. There are chewing mouthparts.

5. The front and middle legs of Tettigonidae and grasshoppers are relatively thin and short, and the hind legs are thick, long and strong.

6. The body colors of Tettigonidae and grasshoppers are green and brown, which is a good protection in the grass. 1. The slender tentacles of the Tettigonidae are longer than the body, compared with those of locusts. 2. Most salamanders are omnivorous, while locusts are phytophagous.

3. Tettigonidae has slender hind legs, while locusts are stout.

Karyotypes of three species of takifugu in China show that takifugu 2n ♂ = 3 1 is a proximal centromere, and Lepidoptera fusca 2n ♂ = 3 1 is also a proximal centromere. Chromosome 2n♂=29 1 of ACIPENSER sinensis is the central centromere chromosome, and the rest are the proximal centromere chromosomes. The sex determination mechanism of these three cockroaches is XO♂/XX♀ type.
