Males disable their own tympana while calling, thereby preventing damage to their hearing; [45] a necessity partly because some cicadas produce sounds up to 120 dB (SPL) [45] which is among the loudest of all insect-produced sounds. [46] The song is loud enough to cause permanent hearing loss in humans should the cicada be at "close range". In ...
Male cicadas make a noise to attract females, which has been described as "the sound of summer". [16] The song of the double drummer is extremely loud—reportedly the loudest sound of any insect [17] —and can reach an earsplitting volume in excess of 120 dB if there are large numbers of double drummers at close range.
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] This call is then received by other tree crickets in the area through a system called sender-receiver matching.
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 ...
The term periodical cicada is commonly used to refer to any of the seven species of the genus Magicicada of eastern North America, the 13- and 17-year cicadas.They are called periodical because nearly all individuals in a local population are developmentally synchronized and emerge in the same year.
Too much light from any building at night can disrupt the rhythms of life for birds, insects and even the humans at the top of the food chain. Green gardening: Too much light from your house at ...
Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night.

The threat to aspens is so great that researchers see a future where the trees no longer grow in the Southwest. A fast-moving infestation of tiny insects threatens the survival of Arizona's aspen ...
