oh they do have that baby stage.. lol..
But they're like 2mm thick and about 25mm long.. sitting under the leaves, so you easily overlook them.
If you don't mind, just squeezing them would perfectly do the job to protect the plant.
Easiest is to look for a group of brown spots under the leaves.. Those are the eggs.
And spraying those eggs, the soap and molasses should kill them off.
