Have you ever seen a one-centimetre-long jumping critter in a leaflitter or close to a pond or a stream and thought that it is some juvenile insect? What you saw was probably an adult pygmy grasshopper, member of the family Tetrigidae. There are more than 2000 described species of those minute jumping insects, and this peculiar family has been around for more than 230 million years, meaninng that pygmies said both ‘hi’ and ‘bye’ to dinosaurs. And yet, we know more about dinosaurs than we do about pygmy grasshoppers.
Scientists from the Ruhr-University and the Bavarian State Collection of Zoology discovered that females of a South American species protrude a Y-shaped organ on their backs to release pheromones and attract males. Found in none of the over 2,500 species of praying mantises worldwide, the behaviour is reported for the first time in the peer-reviewed scientific Journal of Orthoptera Research.
Bird diets provide a real treasure for research into the distribution and conservation of their prey, conclude scientists after studying the Eurasian Eagle Owl in southeastern Bulgaria. In their paper, published in the open-access, peer-reviewed journal Travaux du Muséum National d’Histoire Naturelle “Grigore Antipa”, they report the frequent presence of the threatened Big-Bellied Glandular Bush-Cricket, and conclude that studies on the Eurasian Eagle Owl could be used to identify biodiversity-rich areas in need of protection.
A unique rock carving found in the Teymareh rock art site (Khomein county) in Central Iran with six limbs has been described as part man, part mantis. Rock carvings, or petroglyphs, of invertebrate animals are rare, so entomologists teamed up with archaeologists to try and identify the motif. They compared the carving with others around […]
Commonly known to predate on insects, praying mantises have occasionally been observed to feed on vertebrates, including small birds, lizards, frogs, newts, mice, snakes and turtles. Mostly, such records have either not been scientifically validated or have occurred under induced and human-manipulated circumstances. Nevertheless, no scientific data of mantises preying on fish existed until the […]
The Orthopterists’ Society’s Journal of Orthoptera Research (JOR) joins the growing portfolio of open access titles published on the Pensoft-developed journal publishing platform ARPHA (abbreviation for Authoring, Reviewing, Publishing, Hosting and Archiving). The first issue in collaboration with Pensoft is live on the new journal’s website as of June 2017. While preserving its attractive and […]
