The renown of this katydid rests not on its looks, though, but on its hearing. Montealegre-Z's meticulous studies of the magnificent insect revealed that it has ears uncannily like ours, with entomological versions of eardrums, ossicles and cochleas to help it pick up and analyze sounds.

How do katydids hear?
So here's how a katydid hears. Step one: the two eardrums captures sound, just as ours do. Step two: the tympanal plate sends these vibrations into the fluid-filled auditory vesicle, amplifying them in the process. ... Our cochleas hold between 17,000 and 24,000 hair cells, while the katydids only have 14 to 70.
Do katydids have ears?
Katydids—there are thousands of species—have the smallest ears of any animal, one on each front leg just below the “knee.” But their small size and seemingly strange location belie the sophisticated structure and impressive capabilities of these organs: to detect the ultrasonic clicks of hunting bats, pick out the ...
How do bugs hear?
Many hearing insects have a pair of tympanal organs that vibrate when they catch sound waves in the air. ... An insect also has a special receptor called the chordotonal organ, which senses the vibration of the tympanal organ and translates the sound into a nerve impulse.
How do moths hear?
Moths hear with tympanal membranes, a pair of eardrumlike structures on the thorax. The scientists measured two responses to the sounds: how much the membrane vibrated and the electrical pulse that traveled through the auditory nerve.
How do snakes hear?
Scientists have long struggled to understand how snakes, which lack external ears, sense sounds. Now, a new study shows that sound waves cause vibrations in a snake's skull that are then “heard” by the inner ear. ... Instead, their inner ear is connected directly to their jawbone, which rests on the ground as they slither.
What insect has the best hearing?
In both the animal and the human kingdoms, moths have recently been labeled as having the best hearing in the world. To evade the threat of predators, scientists believe the moth's hearing has evolved to extraordinary levels.
Can katydids hear?
Katydids hear by using a structure called a tympanum, or tympanic organ, one of which is located on each foreleg. There also is a thoracic auditory structure, and some species can communicate through substrate vibration. Males are the primary sound producers, as the females of many species are silent.
How does grasshopper hear?
In fact, grasshoppers have no external ears, but instead hear by means of an organ called a tympanum. However, the tympanum is indeed located near the base of the grasshopper's hind legs, which likely accounts for this belief.
Can Mantis hear?
Praying mantises have sensitive ultrasonic hearing mediated by a single ear located in the ventral midline of the body. The ear comprises two teardrop‐shaped tympana facing each other in a deep, longitudinal groove; they are separated by less than 150 pm. Each tympanum is backed by a tightly adherent tracheal sac.
Do katydids breathe?
Unlike us, the Giant Texas Katydid breathes through tiny holes all over its body called spiracles. Spiracles line the exoskeleton of the insect, allowing air to enter the respiratory system through the trachea, which act as portals to tracheal tubes - the insect's 'lungs'.
Do bugs feel pain?
Over 15 years ago, researchers found that insects, and fruit flies in particular, feel something akin to acute pain called “nociception.” When they encounter extreme heat, cold or physically harmful stimuli, they react, much in the same way humans react to pain.
How do flies hear?
The flies hear using two very small (~1 sq. mm area) ears, located on the front of their thorax, just below where the head/neck attaches - also called the prosternum. The ears are composed of two flexible tympanal membranes joined and linked by a small exoskeletal structure, the presternum.
Do spiders hear?
Spiders don't have ears—generally a prerequisite for hearing. So, despite the vibration-sensing hairs and receptors on most arachnids' legs, scientists long thought spiders couldn't hear sound as it traveled through the air, but instead felt vibrations through surfaces.
Can insects hear you?
Among the many orders of insects, hearing is known to exist in only a few: Orthoptera (crickets, grasshoppers, katydids), Homoptera (cicadas), Heteroptera (bugs), Lepidoptera (butterflies and moths), and Diptera (flies).
Can Butterflies hear?
Butterfly hearing is unusually sensitive to low pitch sounds compared to other insects with similar ears. The structure of the membrane could mean the butterfly can hear a greater range of pitches, which as Katie Lucas and her colleagues postulate, may enhance the abilities of these butterflies to listen for birds.
