Simon King heads for a river to find out what hunts insects at night using thermal and infrared cameras to film bats. The place is plagued by midges and other insects - perfect for bats. Daubenton's bat is an expert at hunting over water, skimming low over the surface to grab the insects as they emerge. Four bats turn up and zoom about as they feed. A Daubenton's bat catches quite large insects, so eats about 1,000 a night. A pipistrelle will eat about 3,000 tiny insects such as midges.
