The whitish-grey females lay eggs on the lower surface of leaf blades mostly during morning hours. The egg is white, cylindrical, distal face somewhat flattened and provided with 2 wings, which run longitudinally and bound the flattened part. The Side under the wings are faintly ribbed and the distal portion between the wings is restricted.
These are one of the serious pests of sorghum in India. The maggots on hatching migrates to the upper surface of leaf, moves along the leaf margin towards the leaf sheath and on entering between the leaf sheath and axis nibbles at the tissue and effects horizontal cut. The growing point dies and succulent and protected by leaf sheath it decays and the maggots feed on this rotten matter. Feeding by boring in to stem of seedlings and cause ‘dead hearts’.
