| The Demons were crying now too, a stridulation that rose above the clamor and seemed to pierce the skull. |
| In all species of Laupala, the male song structure is simple, consisting of a rhythmic train of pulses produced during courtship by stridulation of the forewings. |
| Males of these groups produce sounds by stridulation, which usually involves rubbing the covers of the wings together in a particular way. |
| As with birdsong and insect stridulation, impressive amounts of information are packed into virtually indistinguishable sounds. |
| Many biologists have studied the neural control of sound production since Huber's pioneering work in the 1950s on command systems for stridulation in crickets. |
| It is uproarious, a universal stridulation, as Dr. Edes might put it. |
