Anatomy
Like the other memeber of insecta, crickeks have a three part of body which are head,thorax and abdomen, two antennae and six jointed legs. Exoskeleton is coverd cricket's body. At cricket's head, they have both simple and compound eyes. Compound eyes are using for find the mate or avoidance of predator and simple eyes are really sensitive to light because of their transparent cells, they are allowing the light to pass straight to the retina so that they distinguish the dark and light.[1] In the middle of their body which called thorax. There are fore wing and hind wing. Fore wing is closest to the head while hind wing is not. Hind wing is just like the name, its behind the fore wing and farthest from the head. At the last part of body, there are spiracles. It's using for the breathing. Crickets are jumping insects just like grasshopper. So they must have jumping legs on the abdomen to jump.[2] On the very end, there are cercus and ovipositor. Cerci is a sensory organ, it placed the rear of the abdomen and males have larger cercus. Ovipositor is a reproductive organ and it located between the cercus. [3]
Digestion and Excretory system
The important structure of digestive system is alimentary canal. It control the food until excrete and it can divided by three. Which are foregut, midgut and hindgut. Foregut is the first section of alimentary canal it protects the tough food and stores food. Food goes to second section which is midgut. Midgut produces digestive enzymes to digest food completly. Last section that good goes is hindgut. Hindgut is related with excretory system and it helps the food to excrete. [4]
Reproduction
Many orthopera can make sounds to attract mates, protect their body from predators, and alarm. When they want to produce sounds, they just rub their legs or wings. Cricket make sound two different waies, first one is they use long range so that they could know the mates are near. And when mates come close to other mates, they just make quiet sound. Also they can attract the mates by smell. When female and male crickets are together, male cricket just put the sperm directly to the female's body and female cricket put ovipositor into the wood and ground to lay the eggs.[5] After a few weeks, female cricket starts the hatch the eggs. When mole cricket hatch the eggs, they have a unique chamber to protect the eggs from the predators. The eggs larvae really look like adult however thier wings are not developed yet and reproductive organs. The special thing for cricket is they do not have pupa stages but they just molt like 6 times to 8 times to be adult cricket.[6]
Ecology
We can see crickets really easily even many other orthopeteras.[7] Most orthoptera are hebivores and mostly they have jumping legs on the back side of their body and surely cricket can make sounds and they are detectable.[8] Mole crickets live under the ground, ant crickets live in the ant's nest and camel crickets live in the cave.[9]
