Most cave crickets have very large hind legs with "drumstick-shaped" femora and equally long, thin tibiae, and long, slender antennae. The antennae arise closely and next to each other on the head. They are brownish in color and rather humpbacked in appearance, always wingless, and up to 5 cm (2.0 in) long in body and 10 cm (3.9 in) for the legs.
The burrow acts as a resonator, amplifying the sound. Most male crickets make a loud chirping sound by stridulation (scraping two specially textured body parts together). The stridulatory organ is located on the tegmen, or fore wing, which is leathery in texture. A large vein runs along the centre of each tegmen, with comb-like serrations on ...
Like other species of cricket they produce their calling song by rubbing the ridges of their wings together. The chirp (or trill) of a tree cricket is long and continuous and can sometimes be mistaken for the call of a cicada or certain species of frogs. While male tree crickets have the ability to call, females lack the ability. [5]

Anurogryllus celerinictus, the Indies short-tailed cricket, is a species of cricket in the family Gryllidae.It was described in 1973 by Thomas J. Walker. [1] [2]In January 2019, the noise from its song was proposed as the cause of the Havana syndrome. [3]
Grylloidea is the superfamily of insects, in the order Orthoptera, known as crickets.It includes the "true crickets", scaly crickets, wood crickets and many other subfamilies, now placed in six extant families; some genera are only known from fossils.
Anostostomatidae communicate with sound, both through the air and as ground waves through soil, wood and sand. Adults of both sexes and also nymphs can produce sound. These crickets hear sound using foretibial tympana or other modifications to the tibiae, tarsi and perhaps prothorax .
