A new species of parasitoid wasp that constructs remarkable star-shaped cocoon masses is reported from the biodiversity hot spot Ryukyu Islands. Japanese researchers observed how the wasps construct “stars” after making their way out of the moth larvae they inhabit during their own larval stage. In their study, published in the open-access journal Journal of Hymenoptera Research, the team discuss the ecological significance of the cocoon mass and the evolution of this peculiar structure.
“The species’ striking colouring protects it from birds that prey on insects. They do not snatch the wasp sitting on the tree trunk as they think it will taste bad or that it is dangerous.”
Knowing what species live in which parts of the world is critical to many fields of study, such as conservation biology and environmental monitoring. This is also how we can identify present or potential invasive and non-native pest species. Furthermore, summarizing what species are known to inhabit a given area is essential for the discovery […]
“We thought that it was a good idea to remember this extraordinary year through the name of one remarkable species of Darwin wasp found in seven Mexican States (including Tamaulipas, where the UAT campus is located) and also Guatemala,” comment the researchers who discovered the previously unknown species.
Known to prey on many insects, including honey bees and other beneficiary species, the Asian hornet, which had recently invaded parts of Europe, presents a serious threat to apiculture and even to ecosystems. In their paper, published in the open-access journal Evolutionary Systematics, German scientists share concerns about this fast invader spreading to the north. In early September 2019, a single specimen was collected alive in Hamburg (Germany), representing the northernmost find of the species so far.
A novel approach relying on a short sequence of mitochondrial DNA in conjunction with a lateral image of the holotype specimen was proposed to greatly accelerate species identification and description, especially when it comes to hyperdiverse taxa, such as parasitic wasps.
Specimens kept in the collection of the Institute of Beneficial Insects at the Fujian Agriculture and Forestry University (FAFU, China) revealed the existence of two previously unknown species of endoparasitoid wasps. Originally collected in 2013, the insects are known to inhabit prairies and bushes at above 3,400 m, which is quite an unusual altitude for this group […]
Important group of biocontrol wasps from Central Europe are used to demonstrate the perks and advantages of modern, free-to-use software Representing a group of successful biocontrol agents for various pest fruit flies, a parasitic wasp genus remains largely overlooked. While its most recent identification key dates back to 1969, many new species have been added […]
As many as twenty-one species of parasitoid wasps are described as new to science, following the first ever revision of their genus since its establishment back in 1893. The study simultaneously updates the count of species within the genus (Chromoteleia) to 27 in total, produces a systematic revision of the world’s representatives of this group […]
A myriad of species and genera new to science, including economically important wasps drawing immediate attention because of their amusing names and remarkable physical characters, in addition to work set to lay the foundations for future taxonomic and conservation research, together comprise the latest 64th issue of Journal of Hymenoptera Research (JHR). Two genera (Qrocodiledundee and Tobleronius) named after […]
