Copiphora is a genus of bush crickets or katydids in the subfamily Copiphorinae (coneheads) from southern Mexico, Central America and South America, with a single doubtful species, C. subulata, from Africa.

2018年11月30日 · “Meet Copiphora gorgonensis,” says Fernando Montealegre-Z, discoverer of this six-legged celebrity. The name’s familiar: It’s been splashed across the world alongside photos of the insect’s...

2011年2月23日 · We investigated pinnal function in the katydid Copiphora gorgonensis by combining experimental biophysics and numerical modelling using 3D ear geometries.

2022年9月28日 · We have shown that, in the model species Copiphora gorgonensis, pinnae increase the gain of high ultrasonic frequencies, likely for enhanced detection of their echolocating bat predators. Pinnae serve to expand the auditory dynamic range of the katydid ear beyond the lower frequencies enhanced by the ear canal, enabling the same auditory organ ...

This article describes the acoustic characters of Copiphora gorgonensis, a new species endemic to Gorgona Island National Park, Colombia. It is closely related to C. brevicauda, a congener distributed in the Pacific rainforest of Ecuador and Colombia, and also reported in Central America and other countries of northern South America.

2012年11月16日 · We studied the South American rainforest katydid Copiphora gorgonensis (Orthoptera: Tettigoniidae: Copiphorini) and show that impedance transformation arises from unconventional tympanal mechanics, relying on a lever and fulcrum system and a favorable surface-area ratio to amplify and drive vibrations into the auditory sensory organ . Next, we ...

2022年9月28日 · We investigated pinnal function in the katydid Copiphora gorgonensis by combining experimental biophysics and numerical modelling using 3D ear geometries. We found that the pinnae in C. gorgonensis do not assist in directional hearing for conspecific call frequencies, but instead act as ultrasound detectors.

To investigate this, the surface normal acoustic impedance of the TM is calculated using finite-element analysis in the katydid Copiphora gorgonensis. From this, the reflectance and transmittance are obtained at the TM.

This article describes the acoustic characters of Copiphora gorgonensis, a new species endemic to Gorgona Island National Park, Colombia. It is closely

2023年12月18日 · In the extant Copiphora gorgonensis (subfamily Conocephalinae), resonances are even lower, peaking at 111.13 ± 4.24 (Figures 5E and 5F). 30 Across further species where resonance has been measured, peak values are in a similar range. 30, 52 In the living lipotactines, the formation of a closed cavity provides a much more coherent resonance ...
