New research describes the behavioral and chemical strategies of a Florida ant, Formica archboldi, that decorates its nest with the dismembered body parts of other ant species.
It takes energy to make weapons, but it may take even more energy to maintain them. Because leaf-footed bugs drop their legs, it is possible to measure how much energy they allocate to maintaining this appendage that males use to fight other males.
Representing a group of successful biocontrol agents for various pest fruit flies, a parasitic wasp genus remains overlooked, with its most recent identification key dating back to 1969, even though many new species have been added since then. Through a recent study, published in the open access Biodiversity Data Journal, which also describes one new to science species, Swiss scientists demonstrate the advantages of new-age interactive identification keys, produced with specialised, free-to-use software.
University of Wisconsin-Madison scientists have made a fresh attempt to untangle the scorpion family tree using not the shape and structure of the arachnids' bodies, but the shape of their venom.
Researchers have assembled a new and improved DNA catalogue for the mosquito Aedes aegypti. This tool will help researchers understand the insect's biology, and may lead to new strategies for preventing diseases like Zika and dengue.
New research led by academics at the University of Bristol has discovered that the scales on moth wings vibrate and can absorb the sound frequencies used by bats for echolocation (biological sonar). The finding could help researchers develop bioinspired thin and lightweight resonant sound absorbers.
Plants have evolved ways to make ants defend them from attacks and spread their seeds, and this new study shows how it happened. In a new study breaking down the genetic history of 1,700 species of ants and 10,000 plant genera, researchers found that the long history of ant and plant co-evolution started with ants foraging on plants and plants responding by evolving ant-friendly traits.
Metabarcoding, a technique of mass DNA sequencing, allows for tracing migratory routes of insects, an understudied subject due to technical limitations. A small DNA fragment of the pollen that insects transport is used as a barcode to identify the plant species they visited previously. This British Ecological Society funded study shows that transcontinental pollination mediated by migrating insects is possible and, therefore, various plants located very far apart can mix.

Mosquitoes of the genus Anopheles are well known as primary vectors of malaria. But a new study suggests that Anopheles species, including some found in the United States, also are capable of carrying and transmitting an emerging pathogen, Mayaro virus, which has caused outbreaks of disease in South America and the Caribbean.
