Bark eating caterpillar

Bark eating caterpillar:

Indarbela tetraonis Moore (Arbelidae: Lepidoptera)

 

Pest appearance:

Larva appears blackish making tunnels on the stem and branches.

 

Symptoms of damage:

  • The caterpillars make a small residential hole on the wood normally where the branches fork and from there make superficial galleries inside which they feed on the tissues.
  • The presence of winding galleries on the bark made of powdered bark, faecal pellets and silk webbed together indicates this pest attack.
  • Feeding damage of cambial tissues of small branches by this larva results in drying up of those branches.
