Caterpillars are the larval stage of moths and butterflies and can cause significant damage in ornamental and edible crops. They feed on leaves, buds and flowers, creating irregular holes, chewed edges and contamination with frass. Damage can develop quickly, particularly in protected crops where conditions favour rapid feeding and growth.

• Inspect crops regularly for leaf damage, chewed edges and holes
• Look for caterpillars on leaves, buds and growing points, particularly on young plants
• Check for frass (droppings) on leaves and around the base of plants
• Monitor more frequently during warmer periods, when activity and feeding increase
  

Early detection is important, as caterpillars can cause rapid and visible damage once established.

Caterpillars can be effectively controlled using biological insecticides and beneficial organisms that target the larval stage. Applying treatments at an early stage of infestation and maintaining regular monitoring helps reduce damage and protect crop quality.
