About the mission

  • The purpose of this mission is to understand how likely it is that the alien leaf-mining moths are to be attacked by birds. This is the first large scale study of bird attacks on these leaf-miners anywhere in Europe!
  • We predict that there will be more bird attacks in places where moths have been present for longest.
  • We also predict that where birds are attacking the leaf-mines, they prefer to attack leaf mines on the most infested trees.
  • Do your records support our predictions?
  • The birds attacking the leaf miners are most probably tits, especially blue tits. They seem to feed mostly on the moth pupae.
