Insects
Scientists have discovered that snow flies, small wingless insects, produce antifreeze proteins and generate their own body heat to remain active in subfreezing temperatures as low as -6 degrees Celsius. Researchers at Northwestern University sequenced the insects' genome for the first time, revealing unusual genes and reduced sensitivity to cold pain. The findings, published March 24 in Current Biology, offer insights into adaptations for extreme cold.

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.
Researchers have discovered how a parasitic ant species infiltrates host colonies by manipulating workers to eliminate their own queen. The invader uses chemical camouflage and a targeted spray to incite the attack, securing its takeover. This behavior, observed in Lasius orientalis ants, highlights sophisticated parasitic strategies in insects.

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.
