Crickets, a relatively defenseless, soft-bodied insect, can hear sounds ranging from 2 to at least 100 kHz, with around 70 auditory receptors in each ear. They produce calls ranging from frequencies as low as 600 Hz to as high as 150 kHz, and from pure tones to extremely high bandwidth calls. Cricket Wireless uses a mix of the standard 850 MHz and 1900 MHz blocks for 2G Voice and 3G Data service. Most modern cricket species evolved to communicate at low frequencies (2-8 kHz), which the human ear can detect between 20 and 20, 000 kHz.
The Lebinthini group, a more recent group (30-40 mya), are relatively defenceless, soft-bodied insects that spend the day hidden in cracks, under bark, inside curling leaves, under stones or fallen logs, in leaf litter, or in cracks in the ground that develop in dry weather. Some excavate their own shallow holes in rotting wood or underground and fold in their antennae to conceal their presence.
Crickets discovered that the high-frequency singing (above 15 kHz) is a result of special adaptations in both wing resonances and stridulation (the rubbing together of a pair of wing). Behavioral experiments show that crickets detect sounds over a broad range of frequencies but categorize their auditory world into only two frequency bands: a low-frequency band extending up to ∼15 kHz and a high-frequency band extending from 15 kHz into the ultrasound range.
Crickets divide their auditory world into two broad frequency ranges (categorical perception), one of which is centered on the dominant syllable repetition rate. In the courtship song, single, the frequencies of these oscillations are below ca 70 Hz, with a major component at 30 Hz, the syllable repetition rate.
In the short-winged crickets of the Lebinthini tribe, acoustic communication relies on signals with remarkably high frequencies (>8 kHz) and rich harmonics. Although many of these insects communicate ultrasonically, the main audible range is typically from 2 and 8 khz. The frequency of a cricket’s chirps is consistent with air temperature.

What Frequency Repels Crickets?
Categorical perception in crickets was examined using two human psychophysics paradigms: labeling and habituation-dishabituation. The findings indicate that crickets categorize sound frequencies, particularly distinguishing between attractive sounds above 16 kilohertz. To repel crickets, ultrasonic sound devices emit frequencies around 30 kHz, which are inaudible to humans but effective for pest control.
These innovative devices and applications aim to restore tranquility during evenings by utilizing ultrasound to deter crickets without releasing harmful fumes, making them a non-toxic alternative to traditional pest repellents.
The response of crickets to ultrasonic frequencies is supported by scientific research, which shows that different cricket species have varying frequency ranges. Additionally, crickets chirp as a means of communication, primarily for attracting mates and establishing territory; this stridulation varies with temperature, as warmer conditions increase chirping frequency. Salt mixed with water is another effective repellent, capable of killing crickets at sufficient concentrations.
Ultrasonic pest repellers function by emitting high-frequency sound waves that interfere with pests, potentially yielding psychological reactions that deter them. Specifically, frequencies between 20 kHz to 100 kHz are often utilized, targeting various household pests like crickets and rodents. Enhanced pest control methods using ultrasound demonstrate significant reductions in cricket populations, offering efficient solutions for pest management.
Why Do Crickets Chirp?
Crickets communicate primarily through chirping, a behavior exhibited mainly by males to attract females, deter other males, and establish territory. This sound, known scientifically as stridulation, occurs when male crickets rub their wings or body parts together, generating the identifiable chirp. Temperature has a significant influence on the frequency of chirping; warmer conditions result in more chirps. Crickets are particularly vocal at night, using their chirps as part of their mating rituals, which serve not only to attract potential mates but also to alert other males of their presence.
Despite their commonness in rural settings, few know the motivations behind this behavior. Male crickets produce distinct chirping songs to differentiate themselves to female crickets, who must recognize their species. Additionally, these repeated chirps can vary among cricket species, serving specific purposes in mating calls. Interestingly, while nocturnal chirping helps crickets avoid daytime predators, studies have shown that this behavior might attract predators like cats, as they follow the sound.
Crickets' incessant nighttime chirping ceases the moment one approaches, allowing for a challenge in observing them. Nonetheless, understanding the underlying reasons and mechanics of their chirping offers insight into their communication methods. Overall, the primary motive for a cricket's chirping is to find a mate, with their unique songs reflecting the diversity among cricket species, providing both information on mating and a method of defending territory. As nocturnal insects, crickets utilize their chirping to enhance their mating success while navigating the risks posed by predators.
Why Do Crickets Have Two Different Ranges Of Hearing Frequencies?
Crickets exhibit specialized hearing abilities tailored for communication and predator avoidance. They primarily communicate using low-frequency sounds (2-8 kHz), while also detecting higher frequency echolocation signals from bats, their natural predators. Research shows that crickets possess a hearing range from 2 to at least 100 kHz and have approximately 70 auditory receptors in each ear. This allows them to divide their auditory perception into two distinct frequency bands, enhancing their ability to respond to different environmental sounds.
Directional hearing was examined through neurophysiological techniques, focusing on the activity of bilateral AN1 neurons, crucial for processing auditory cues. Two subpopulations of low-frequency sensitive auditory afferents, identified as medial terminating (MT) and bifurcating (BC), contribute to the auditory responses in crickets. Temporal tuning experiments demonstrated that crickets are attracted to specific syllable repetition intervals, emphasizing their selective auditory preferences.
In addition to communication, crickets, like lacewings, must also navigate their auditory environment to avoid predation. This dichotomy in frequency sensitivity allows crickets to thrive, positioned as both listeners and evaders in their habitat. While the majority of insects and animals produce complex sound patterns, field crickets typically generate pure-tone calling songs, suggesting an evolutionary adaptation that enhances their communication while minimizing risks.
Citing studies on acoustic evolution, it appears that despite the variability in acoustic behavior across cricket clades, certain species retain notably refined ear structures, closely resembling mammalian auditory mechanisms. Understanding these unique auditory adaptations sheds light on crickets' survival strategies, highlighting their capacity for behavioral modification in response to acoustic contexts.
How Do Crickets Sing So Loudly?
The familiar sound of cricket chirping comes from male crickets attempting to attract mates. This characteristic song isn't produced by vocal cords but through the fascinating mechanism of their wings. Male crickets create chirps by rubbing a scraper-like edge on one wing against a file-like surface on the other, in a process known as stridulation. Interestingly, only adult male crickets have the capability to chirp, as females lack the specialized wing structures necessary for producing sound.
Crickets typically chirp at night, when they are most active as nocturnal creatures. Their chirps can often be heard in homes, usually increasing in volume when approached or disturbed. The sound varies among different species; louder and higher-pitched chirps generally make a male more appealing to potential mates.
The mechanics of chirping involve the simultaneous elevation of the wings, with one usually positioned slightly higher than the other. The ridges and serrations on the wings create the distinct chirping noise when rubbed together. Overall, cricket chirping plays a crucial role in their mating rituals, with each species having unique melodies that serve to attract females. In addition to crickets, cicadas produce even louder sounds, employing a different method of sound production using their wing coverings, resembling a tiny violin.
In conclusion, male crickets produce their characteristic chirping sounds through the intricate interaction of their wings, serving primarily the purpose of attracting female mates. This acoustic display is a vital aspect of their reproductive behavior and highlights the unique adaptations found in these insects.

What Frequency Does A Cricket Call?
The dominant frequency (Fd) of cricket calling songs typically falls between 2 to 8 kHz, primarily due to the small physical size and functioning of their stridulum. However, some Eneopterinae crickets, such as Eneoptera guyanensis, have been recorded calling at frequencies of 10-15 kHz, with some producing modulated calls that incorporate both low and high frequencies. Generally, modern cricket species have adapted to communicate effectively in the lower frequency range that aligns with human auditory perception, which spans from 20 Hz to 20 kHz.
Cricket sound frequencies, measured in hertz, are influenced by wing movement speed and size; larger crickets emit lower-pitched sounds compared to smaller counterparts. While tonality of cricket calls has remained consistent (2-9 kHz) over 200 million years of evolution, crickets have developed specialized adaptations for high-frequency singing. In their calling songs, the dominant frequency is typically the lowest harmonic, and variations can be observed depending on species.
Research indicates crickets possess around 70 auditory receptors per ear, allowing them to detect sounds from 2 to at least 100 kHz. The physics of cricket song production, including the principles of low-frequency driving and sound radiation efficiency, hold potential applications in micro-scale technology. Current studies continue to explore the relationships between chirp rates, frequency, and overall sound amplitude in various cricket species, elaborating on their complex acoustic communication mechanisms.
Do Eneopterinae Crickets Call With A High FD?
Some Eneopterinae crickets are recognized for their calling frequencies (Fds) ranging from 10 to 15 kHz, with the species Eneoptera guyanensis notable for its modulated call that incorporates both low and high frequency components. The study of Fd evolution is conducted within the phylogeny of the Eneopterinae subfamily to understand the transformation patterns in their calling behaviors. Typically, male crickets produce loud, pure-tone calls to attract mates by rubbing their forewings, with the dominant frequency of these calls usually falling between 2 to 8 kHz.
This frequency range is largely influenced by the physical constraints tied to their small size and the functioning of their stridulum. Despite this, some species in the subfamily have adapted to produce higher frequencies. It is noted that there is a convergence towards high-frequency calling among certain species of the genus Eneoptera. The evolutionary adaptation is significant where Eneoptera guyanensis features an addition of a high frequency component to its ancestral call, leading to frequency modulation.
This transformation reflects an adaptive radiation in high-frequency calling within the subfamily, especially evident in male crickets from the tribe Lebinthini, which sometimes produce ultrasonic calls. The shift from low to high Fd represents a remarkable departure from the typical calling patterns found in crickets, thereby expanding the ecological and evolutionary understanding of acoustic signaling among these insects.

You debunked nothing. The explanation behind “God’s Chorus of Crickets” is that each frame has been slowed down to the lifespan of a human. You’ve taken an entire section of frames and slowed it down, instead of a single frame. You’ve also assumed the dates. An adult cricket lives 6 weeks, but their entire lifespan is 3 months. That would change the speed. Why is it others who have tried this same experiment have results that are successfully similiar to Jim Wilson’s? youtu.be/uanB6Qn8v5M
