Cricket

Because crickets are found all over the world, there are There are thousands of different subspecies, so individual differences are relatively large, but generally the body size of crickets is small to medium, and a few are huge. The body color is almost all dark brown or black.
Crickets have round heads, broad chests, and slender antennae. Savory mouthparts. Some have large jaws that are stronger than bites. Each foot has three tarsal segments, and the front and middle feet are similar and of the same length; the hind feet are prosperous and good at leaping; the hearing organ on the tibia of the front foot is larger on the outside than on the inside.
The ovipositor is exposed, needle-shaped or spear-shaped, and consists of 2 pairs of tube valves. Both males and females have a pair of tail hairs on their abdominal ends. There is a pair of short rod-shaped abdominal spines at the male abdominal end. Females are individually larger, with needle-like or spear-like ovipositing tubes exposed and small wings. There are articulators on the male forewings, which are composed of scrapers, friction veins and articulating mirrors on the wing veins. The forewings are raised and rubbed, and then the sound mirror is vibrated to produce a tone.
Crickets are mostly barrel-shaped, with strong hind legs and filamentous antennae that are longer than their body. There are two long tail threads at the end of the abdomen. If it is a female, there is also an oviposition tube that is longer than the tail thread. There is another trick to distinguish between males and females. The one with obvious bumpy patterns on the wing feathers is male, and the one with straight wing patterns is female. of. The most special thing is that his hearing aids are on the front of his feet.
