castanets

"One reasonably well-understood example of a percussive mechanism involving two-body parts is found in members of the Austrlian moth genus, Hecatesi (Bailey, 1978). In these moths an area of the costae of the fore wings is modified to form small hard knobs whichhave been called castanets. These are repeatedly struck together at the top of the wing stroke to produce sounds which have given these insects the popualr name of 'whsitling moths'." [1]

chirp

"A sound which may consist of one or more syllables or pulses and which is normally heard by the human ear as a unitary event. Usually applied to the songs of crickets and related insects." [1]

"as equated to one movement (= Silbe, G.), Broughton, now abandoned and deprecated as over-restriced." [2]

"Preferred unitary dictionary sense, as first parameter of analysis: the shortest unitary rhythm element of a soun emission that can readily be distinguished as such by the human ear." bib]57890[/bib]
