Lay the leaves in a pan on a wet paper towel.
Do you see the two white dots on the closest leaf? Those are eggs.
Put a damp paper towel over the eggs.
Check daily and mist with water to keep moist. When the egg turns dark or is clear with a dark spot, put the leaf in a jar with a small damp piece of paper towel.
This egg will hatch within a few hours. The new larvae will then eat it's egg for nourishment.
