The sounds of crickets courting and flies flying familiar to many of us, but have you heard a rice weevil larva eating inside a wheat kernel, a termite cutting a piece of wood, or a grub chewing on a root?  Modern insect detection and control technology makes use of these subtle signals, sampled below.
Most of the sound files in this library were selected from noise-free sections of recorded signal, but you can hear some typical background noises mixed with insect sounds at I below.  The insect sounds have higher frequencies and shorter durations that make them relatively easy to separate from background (see discussion in .pdf icon). Several different methods have been developed to identify sounds of particular insect species, and at least one author ( .pdf icon )  has tested a method against multiple signals below.

Note:  This page contains links to sound ( .wav files icon or .wav) files, and accompanying information in Link to Adobe Acrobat (.pdf) files as well as links to pictures or other information about each species in the Encyclopedia of Life  Encyclopedia of Life symbol or Featured Creatures Featured Creatures symbol.

 Some of the sounds are low in intensity, and it may be necessary to turn up the speaker volume to hear them.  Also, many sound players like to deemphasize low frequencies.  If your player has an equalizer and you can't hear the sounds, turn up the frequencies between 600 and 1500 Hz.

If the sound does not play well over the internet,  you can right click on the file, and then click Save Target As  to download the file to your desktop or elsewhere on your computer, where it may play better.
