Brown pasture looper

Constraint - Brown pasture looper


  • Young caterpillars move with a characteristic looping motion 

  • Caterpillars are grey/brown with black and cream stripes

  • Adult moths are up to 20 mm long, dusty brown with grey and brown streaks on forewings


  • Seedlings/plants have leaves chewed from the edges towards the middle of the leaf

  • Caterpillars can often be observed on the leaf

  • Damage is frequently worse near fence lines adjacent to pasture paddocks


  • Yield penalty is rare


Brown pasture loopers are easily controlled by insecticides. Segregation of canola paddocks from pasture paddocks can also reduce the risk of infestation.
