or are carried by wind to the young growing points or flowers where they spin silk around terminal leaves or petals.
Caterpillars feed mainly on leaves, flowers and buds. Older caterpillars loosely spin newly opened leaves together such that subsequent growth leads to an untidy

instars subsequently develop. Once larval development is complete the larva spins a cocoon inside the aphid cuticle, causing it to swell. The cuticle turns
larva is about 2 mm long. At the end of the last larval stage, the larva spins a white cocoon near a leaf vein and pupates within it. By closely monitoring
