They belong in the same order of insects as grasshoppers and crickets and are among the many species that communicate acoustically.<\/p>\n<p>Male bush crickets are prolific callers \u2013 and each species has its own call to advertise their fitness to females. They call in different frequency bands and for different lengths of time, so that they can make themselves heard to the right potential mate. <\/p>\n<p>In South Africa, there are about 169 species of bush crickets. Of these, about 123 have an <a href=\"https:\/\/www.iucnredlist.org\/\">IUCN Red List<\/a> status. The species <em>Thoracistus thyraeus<\/em> is considered critically endangered. But a study by our guest in today\u2019s episode of Pasha, Aileen van der Mescht, a postdoctoral researcher at the department of zoology and entomology at the University of the Free State, found that they might be more resilient than was thought. <\/p>\n<p>She recorded the calls of nocturnal bush crickets to determine how the different species were distributed across the landscape and what variables drive the distribution. The <a href=\"https:\/\/www.tandfonline.com\/doi\/abs\/10.1080\/09524622.2021.1925589\">research<\/a> identified 11 species in the study area. Those that used a higher frequency for their specific call tended to be recorded in more open habitats like grassland. Lower frequency callers occupied woodier areas \u2013 both plantations and indigenous forests. <em>Thoracistus thyraeus<\/em> was present in a forestry plantation where it wasn\u2019t expected to be.<\/p>\n<p><em>Thoracistus thyraeus<\/em> is also known as the Inflated Seedpod Shieldback. Its blown-up thorax looks like a seedpod and amplifies its call. <\/p>\n<p>Bush crickets are often well camouflaged to avoid being eaten by predators. They feature in many food webs and play an important role in recycling nutrients. Aileen talks about some of their interesting features and their <a href=\"https:\/\/theconversation.com\/pasha-121-why-we-need-mosquitoes-166430\">value<\/a> in ecosystems. <\/p>\n<hr>\n<p><strong>Photo:<\/strong><br \/>\u201cMale, Thoracistus thyraeus in KwaZulu Natal, Karkloof swamp.\u201d<br \/>\nby Claudia Hemp found <a href=\"http:\/\/orthoptera.speciesfile.org\/Common\/basic\/ShowImage.aspx?TaxonNameID=1141648&amp;ImageID=196109\">here<\/a><\/p>\n<p><strong>Music:<\/strong><br \/>\n\u201cHappy African Village\u201d by John Bartmann, found on <a href=\"http:\/\/freemusicarchive.org\/music\/John_Bartmann\/Public_Domain_Soundtrack_Music_Album_One\/happy-african-village\">FreeMusicArchive.org<\/a> licensed under <a href=\"https:\/\/creativecommons.org\/publicdomain\/zero\/1.0\/\">CC0 1<\/a>.<\/p>\n<p>\u201cOne Night In Africa\u201d by John Bartmann, found on <a href=\"https:\/\/freemusicarchive.org\/music\/John_Bartmann\/Royalty-Free_Soundtrack_Music_Album_Two\/one-night-in-africa\">Free Music Archive<\/a> licensed under under a <a href=\"https:\/\/creativecommons.org\/licenses\/by-sa\/4.0\/\">Attribution-ShareAlike License<\/a>.<\/p>\n<p> <a href=\"https:\/\/theconversation.com\/africa\/\">Source: The Conversation<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Bush crickets \u2013 or katydids, as they are also known \u2013 are fascinating creatures.
