Anti-Predator Defences and Ecology of Neotropical Forest Katydids, Especially the Pseudophyllinae

Wing mechanics, vibrational and acoustic communication in a new bush-cricket species of the genus Copiphora (Orthoptera: Tettigoniidae) from Colombia

“…3, see also Morris et al 1994). Similar to C. (Belwood, 1988(Belwood, , 1990Belwood and Morris, 1987;Morris et al, 1994;Römer et al, 2010). Eavesdropping seems to explain why some bush-crickets use such bewilderingly high principal carriers (Belwood and Morris, 1987;Falk et al, 2015;Montealegre-Z et al, 2006;Montealegre-Z et al, 2011b;Morris et al, 1994;Sarria-S et al, 2014).…”

Sound signalling in orthoptera

“…Some bats attack flying insects (aerial-hawking) while others take stationary insects from the vegetation (foliage-gleaning). Bats feed extensively on Orthoptera: 42% of the insects eaten by Micronycteris hirsuta in Panama, for example, are bushcrickets (Belwood, 1990). As well as the calls made by bats, ultrasound is generated by, for example, carnivorous tettigoniids, the calls of small terrestrial mammals, and disturbances to vegetation.…”

Synonymies of Wasp-Mimicking Species within the Katydid GenusAganacris(Orthoptera: Tettigoniidae: Phaneropterinae)

“…At night, rapid movement is curtailed, and activity on leaves becomes more cautious, no doubt in response to more common nocturnal predators such as night birds, leaf-gleaning bats, and various predatory arthropods (spiders, scorpions, centipedes, and predaceous katydids) (Belwood & Morris 1987, Belwood 1988, 1990, Nickle & Castner 1995.…”

“…2) (Belwood 1988), commonly found from Mexico to Colombia, while several species of glossy black predatory wasps including Hemipepsis and related genera (Pompilidae) may act as multiple models for A. velutina. Belwood (1990) reported effects of predation on the singing behavior of A. insectivora on Barro Colorado Island, Panama. Leafgleaning bats often use echolocation for general orientation but tend to locate their katydid prey passively by listening for the sounds they make.…”

“…Leafgleaning bats often use echolocation for general orientation but tend to locate their katydid prey passively by listening for the sounds they make. Four of the six katydid species taken by Micronycteris hirsuta on Barro Colorado Island in Panama call in the 23-27 kHz range, suggesting which prey are taken depends on whether the bat can hear their call or not (Belwood 1990).…”
