Researchers have discovered a new spider species in the Indian Himalayas, Theridion himalayana, which displays a striking "happy-face" pattern and polymorphic color variations nearly identical to its famous Hawaiian relative. Despite the physical resemblance, DNA analysis confirms it is a distinct lineage that evolved independently, prompting new questions about the evolutionary purpose of these patterns and the spider's specific association with ginger plants.

The venom of forest ants and horse ants contains numerous substances that protect the insects from pathogens. Researchers at Martin Luther University Halle-Wittenberg (MLU) and Freie Universität Berlin have succeeded for the first time in identifying and characterising these novel antimicrobial substances in the insects’ venom. These substances are peptides, small protein molecules. The study, published in the journal ‘Science Advances’, provides new insights into nest protection and the management of microbes in insect communities. At the same time, the newly discovered substances could provide fresh impetus for medical drug discovery.

A new report shows that queen bumblebees are fast learners, able to memorize flower scents more quickly than worker bumblebees. The work could shed light on how cognition first evolved and help scientists preserve a critical ecological link. 

Even large and conspicuous insects remain unknown to science. This is highlighted by a new study from the Natural History Museum Denmark, where researchers have discovered and described 61 new species within the rove beetle genus Platydracus.
