Honey bees perform their waggle dance more precisely when more hive mates watch, according to a new study. Researchers found that dancers adjust their movements to attract followers, sacrificing accuracy for engagement when audiences are small. The findings highlight the social dynamics of bee communication.

Scientists from Georgia Tech and MIT have developed a mathematical model explaining how female Aedes aegypti mosquitoes navigate to humans. The study shows insects respond independently to dark visual cues and carbon dioxide rather than following each other. Findings could improve mosquito traps and disease control.
New research reveals that bumble bees often prevail in direct confrontations with invasive Argentine ants at feeding sites, but these encounters lead to prolonged aggression that reduces their food collection. This added pressure exacerbates challenges for bumble bee colonies already facing habitat loss, diseases, and pesticides. The study highlights how such interactions could impact these vital pollinators.

An international team of researchers has discovered a 151-million-year-old fossil of a non-biting midge in Australia, the oldest known from the Southern Hemisphere. This find, named Telmatomyia talbragarica, reveals freshwater adaptations previously linked only to marine species, suggesting the Chironomidae family originated in Gondwana. The discovery reshapes understanding of ancient insect biogeography.
