The mandibles of a bull ant. Insect mandibles are a pair of appendages near the insect's mouth, and the most anterior of the three pairs of oral appendages (the labrum is more anterior, but is a single fused structure). Their function is typically to grasp, crush, or cut the insect's food, or to defend against predators or rivals.
Cricket flour is used in protein bars, pet foods, livestock feed, nutraceuticals, and other industrial applications. The United Nations says that the use of insect protein, such as cricket flour, could be critical in feeding the growing population of the planet while being less damaging to the environment. [58]
A chewing insect has a pair of mandibles, one on each side of the head. The mandibles are caudal to the labrum and anterior to the maxillae. Typically the mandibles are the largest and most robust mouthparts of a chewing insect, and it uses them to masticate (cut, tear, crush, chew) food items.
The Jerusalem cricket's song features a characteristic drumming sound Ammopelmatus fuscus Idahoan "potato bug" Ammopelmatus fuscus. Similar to true crickets, each species of Jerusalem cricket produces a different song during mating. This song takes the form of a characteristic drumming in which the insect beats its abdomen against the ground.
Mole crickets are the only insects that construct a sound-producing apparatus. Given the known sensitivity of a cricket's hearing (60 decibels), a night-flying G. vineae female should be able to detect the male's song at a range of 30 m; this compares to about 5 m for a typical Gryllus cricket that does not construct a burrow.

Mandibulates make up 70 percent of the animal kingdom, but Odaraia alata sported mandibles before it was cool. A Startling Discovery Found Mandibles in 500-Million-Year-Old Fossils. It Doesn't ...
The mandibles cut and crush food, and may be used for defense; generally, they have an apical cutting edge, and the more basal molar area grinds the food. They can be extremely hard (around 3 on Mohs , or an indentation hardness of about 30 kg/mm 2 ); thus, many termites and beetles have no physical difficulty in boring through foils made from ...
