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.
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 […]
In the Neotropics, there is a whole group of so-called glassfrogs that amaze with their transparent skin covering their bellies and showing their organs underneath. A recently discovered new species from Amazonian Ecuador, however, goes a step further to fully expose its heart thanks to the transparent skin stretching all over its chest as well […]
A total of fifteen new species of parasitic wasps have been described from across the Neotropical region. Apart from belonging to a peculiar group of wasps distinct with large and elongated bodies, the new insects also draw attention with the curious names they have been formally assigned with. Among them, there are species named after […]
Having collected thousands of moth and butterfly species from across Costa Rica, famous ecologist Daniel Janzen, University of Pennsylvania, and his team were yet to find out many of their names. When they sought help from Dr. Gunnar Brehm, the taxonomist realised he needed too much time to describe species in the framework of an […]
Out of more than 110 allegedly well-studied mouse-eared bat species, there turns out to be one that has been keeping its diet a mystery. Belonging to the largest group of bats, known to be feeding on insects exclusively, the widely common Black mouse-eared bat (Myotis nigricans) is found to also seek fruits. The Brazilian team […]
