The Mole - Netflix
"The Mole" follows a group of 12 players as they try to figure out who among them is The Mole, a saboteur trying to keep them from winning money. Players must decide who they think The Mole is and then learn as much about him or her as they can, because, at the end of each one-hour episode, the player who knows the least about The Mole is immediately "Executed" from the game. In the final dramatic episode, The Mole is revealed and one of two final players wins a substantial cash prize.

The Mole - Mole cricket - Netflix
Mole crickets are members of the insect family Gryllotalpidae, in the order Orthoptera (grasshoppers, locusts, and crickets). Mole crickets are cylindrical-bodied insects about 3–5 cm (1.2–2.0 in) long as adults, with small eyes and shovel-like fore limbs highly developed for burrowing. They are present in many parts of the world and where they have arrived in new regions, may become agricultural pests. Mole crickets have three life stages, eggs, nymphs, and adults. Most of their lives in these stages is spent underground, but adults have wings and disperse in the breeding season. They vary in their diet; some species are vegetarian, mainly feeding on roots; others are omnivores, including worms and grubs in their diet, while a few are largely predatory. Male mole crickets have an exceptionally loud song; they sing from a subsurface burrow that opens out into the air in the shape of an exponential horn. The song is an almost pure tone, modulated into chirps. It is used to attract females, either for mating, or for indicating favourable habitats for them to lay their eggs. In Zambia, mole crickets are thought to bring good fortune, while in Latin America, they are said to predict rain. In Florida, where Neoscapteriscus mole crickets are not native, they are considered pests, and various biological controls have been used. Gryllotalpa species have been used as food in West Java, Vietnam, and the Philippines.
The Mole - Song - Netflix
Male mole crickets sing by stridulating, always underground. In Gryllotalpa gryllotalpa the song is based on an almost pure tone at 3.5 kilohertz, loud enough to make the ground vibrate 20 cm all round the burrow; in fact, the song is unique in each species. In Gryllotalpa gryllotalpa, the burrow is somewhat roughly sculpted; in Gryllotalpa vineae, the burrow is smooth and carefully shaped, with no irregularities larger than 1 mm. In both species, the burrow has twin openings at the soil surface; at the other end is a constriction, then a resonating bulb, and then an escape tunnel. A burrow is used for at least a week. The male positions himself head down with his head in the bulb, his tail near the fork in the tunnel. Mole crickets stridulate like other crickets by scraping the rear edge of the left fore wing, which forms a plectrum, against the lower surface of the right fore wing, which has a ratchet-like series of asymmetric teeth; the more acute edges face backwards, as do those of the plectrum. The plectrum can move forward with little resistance, but moving it backwards makes it catch each tooth, setting up a vibration in both wings. The sound-producing stroke is the raising (levation) of the wings. The resulting song resembles the result of modulating a pure tone with a 66-Hz wave to form regular chirps. In G. vineae, the wing levator muscle, which weighs 50 mg, can deliver 3.5 milliwatts of mechanical power; G. gryllotalpa can deliver about 1 milliwatt. G. vineae produces an exceptionally loud song from half an hour after sunset, continuing for an hour; it can be heard up to 600 m away. At a distance of 1 m from the burrow, the sound has a mean power over the stridulation cycle up to 88 decibels; the loudest recorded peak power was about 92 decibels; at the mouths of the burrow, the sound reaches around 115 decibels. G. gryllotalpa can deliver a peak sound pressure of 72 decibels and a mean of about 66 decibels. The throat of the horn appears to be tuned (offering low inductive reactance), making the burrow radiate sound efficiently; the efficiency increases when the burrow is wet and absorbs less sound. 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. The loudness of the song is correlated with the size of the male and the quality of the habitat, both indicators of male attractiveness. The loudest males may attract 20 females in one evening, when a quieter male may attract none. This behaviour enables acoustic trapping; females can be trapped in large numbers by broadcasting a male's song very loudly.
