Oecanthus nigricornis

Bell (10) describes four discrete types of such movements in O. nigricornis, ranging from simple fluttering of the hind wings, to a type of push-up display common in court- ing gryllids, to an infrequent yet dramatic shaking of the substrate vegetation, which can cause an approximately 1-cm displacement of a leaf.
These signals can aid females in localizing males during pair formation (24, 76, 115). But often in gryllids, as in O. nigricornis, vibratory signals are produced only after the pair have made contact and thus appear to play a role in courtship. [1]
