The anatomical parts used to produce sound are quite varied: the most common system is that seen in grasshoppers and many other insects, where a hind leg scraper is rubbed against the adjacent forewing (in beetles and true bugs the forewings are hardened); in crickets and katydids a file on one wing is rubbed by a scraper on the other wing; in ...
Naucoridae is a small family of insects commonly known as the creeping water bugs and saucer bugs. They are similar in appearance and behavior to Belostomatidae (giant water bugs), but considerably smaller, at 0.5–2 cm (0.2–0.8 in) long. Naucoridae are found around the world, but the greatest diversity is in tropical regions.

The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, water gliders, water skimmers or puddle flies.
They have a pair of compound eyes, with an ocular tubercle behind and above each eye, made up of three lenses (called triommatidia). [12] They feed on sap using sucking mouthparts called stylets , enclosed in a sheath called a rostrum , which is formed from modifications of the mandible and maxilla of the insect mouthparts.
The historical background of natural sounds as they have come to be defined, begins with the recording of a single bird, by Ludwig Koch, as early as 1889.Koch's efforts in the late 19th and early 20th centuries set the stage for the universal audio capture model of single-species—primarily birds at the outset—that subsumed all others during the first half of the 20th century and well into ...
In these insects, the volume of the film is small enough, and their respiration slow enough, that diffusion from the surrounding water is enough to replenish the oxygen in the pocket of air as fast as it is used. The large proportion of nitrogen in the air dissolves in water slowly and maintains the gas volume, supporting oxygen diffusion ...

The pondskaters or water striders (Gerridae) are also associated with water, but use the surface tension of standing water to keep them above the surface; [44] they include the sea skaters in the genus Halobates, the only truly marine group of insects.
