First it cleans a portion of leaf blade with its radula, then it forms a fold in its foot connecting its genital pore with its mucous pedal gland. The egg mass passes along this fold and the pedal gland is used to cement the egg capsule to the leaf blade. This process takes about ten minutes, during which time the snail's body and shell oscillate from side to side. After this, the snail moves forward slightly and repeats the process, eventually producing a series of flattened capsules that overlap each other giving a shingled effect. A typical egg string may contain 45 eggs and be long.
