1. Egg: Eggs laid singly in the tissues of the tender leaves on the sides facing the stem. Eggs are hyaline and turn pale yellow as they mature.

2. Nymph: Newly hatched nymphs are transparent but turn yellowish white after the first moult and possess darker legs, head and antennae.

3. Pupa: Pupation takes place inside the rolled leaves and appendages and wings are clearly visible.

4. Adult: Adult is 1 mm long, dark brown to black in colour with fringed wings. Male is smaller, more slender than female. It reproduces parthenogenetically since males are seldom seen in the population.
