Oct 3, 2025
A swarm of hoverflies baffled scientists on an oil rig in the North Sea, revealing their migratory patterns and role as pollinators. These tiny insects can carry pollen from over 100 plant species across vast distances. Meanwhile, researchers uncover surprising growth rates in Amazon trees due to increased CO2, though concerns about deforestation remain. Plus, the intriguing sounds of coral reef fish are explored, as scientists document their vocalizations to monitor reef health in a non-disruptive way.

ANECDOTE

Oil Rig Naturalist Sparks Study

  • Engineer Craig Hanna observed thousands of hoverflies landing and staying still on an oil rig for hours before taking off together.
  • He collected specimens and sent them to the University of Exeter for study, sparking scientific interest.

Hoverflies Transport Diverse Pollen Far Offshore

  • University of Exeter researchers found 66 hoverflies carrying pollen from over 100 plant species after ocean crossings.
  • Wind-trajectory analysis suggests some flies traveled more than 300 miles from places like the Netherlands and Denmark.

Long-Distance Pollination Could Aid Plant Adaptation

  • Long-distance pollen carried by hoverflies could introduce new genes to distant plant populations and aid adaptation.
  • Researchers plan to test whether pollen survives the journey and can actually fertilize plants.
