Larvae <20mm long, white and mottled with brown when fully grown. More information in Bleszinski & Collins (1962).

  Life History & Pest Status

  
  

  The ‘yellow top borer’. Eggs c. 240, scale-like, overlapping, laid in 3-5 rows in masses of 4-100. Larvae hatch after 3-8 days. Larvae pupate after 22-45 days. Adults emerge after a pupation of 6-18 days.
  
  A serious pest of Saccharum officinarum, S. spontaneum & S. fuscum, (sugar cane) Graminaceae: larvae feed on the central whorl of leaves, which dries up forming a dead heart. Crop yields can fall by 70% in cases of heavy infestation. Also a pest of Andropogon sorghum (sorghum), Oryza sativa, (rice). Also feeds on Parapholis filiformis = Rottboellia compressa (Poaceae).

  The internal feeding larvae attack all stages of the plant.
  
  Kapur (1964) considered its exact identification there as a rice stem borer was in doubt although it was undoubtedly a pest of sugar cane in India..
