Neuroscientists have recorded the first video footage of a tiny killer fly catching its prey in mid-air, in a study of how the insect picks its targets.
They recorded high-speed video footage of the killer flies pursuing fruit-fly prey, as well as different sizes of moving beads.
Apparently the diminutive predators, just 4mm long, are not much good at judging the size of a target – so they decide whether to strike partly based on how fast a potential meal is buzzing past.
The experiments appear in the journal Brain, Behaviour and Evolution.
