For 157 years, scientists have wished they could understand the evolutionary relationships of a curious South American ground beetle that was missing a distinctive feature of the huge family of ground beetles (Carabidae). Could it be that this rare species was indeed lacking a characteristic trait known in over 40,000 species worldwide and how could […]
With 3,000 known species and thousands more left to describe, the wasps of the subfamily Microgastrinae are the single most important group of parasitoids attacking the larvae of butterflies and moths, many of which are economically important pests. Consequently, these wasps have a significant impact on both the world’s economy and biodiversity. Due to their […]
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 […]
Mistakes can occur in any environment, but what if the records we read about are actually incorrect? The case of unqualified scientists publishing false records of insects in the Murmansk oblast of Russia is described in the recent paper in the open-access journal Arctic Environmental Research.
When, in 2014, Brazilian researchers stumbled across a never-before-seen red-eyed leafhopper feeding inside the rosettes of bromeliads, growing in the restingas of southeastern Brazil, they were certain it was a one-of-a-kind discovery. Described as new-to-science species, as well as genus (Cavichiana bromelicola) and added to the sharpshooter tribe Cicadellini, it became the first known case […]
Killing and eating of potential competitors has rarely been documented in the zoological literature, even though this type of interaction can affect population dynamics. In a recent publication in the open-access journal Subterranean Biology, Brazilian scientists presented their notes regarding the predation of an assassin bug by a spider in Neotropical caves. Underground, where food resources are scarce, such events might be possible as a result of ecological pressures imposed by the hostile environment, hypothesise the researchers.
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 […]
In an unexpected discovery from New Zealand, two species of narrowly distributed moths were described as new species. Interestingly, both Arctesthes titanica and Arctesthes avatar were named after mythological deities and top-grossing blockbusters by famous filmmaker James Cameron: Titanic and Avatar, respectively.
Earlier this year, a research article triggered a media frenzy by predicting that as a result of an ongoing rapid decline, nearly half of the world’s insects will be no more pretty soon Amidst worldwide publicity and talks about ‘Insectageddon’: the extinction of 40% of the world’s insects, as estimated in a recent scientific review, a critical […]
