Eggs on plant leaves are often laid by insects as a way to protect and provide food for their offspring. The eggs can hatch into larvae that feed on the plant, helping the insect offspring grow and develop.
Usually the underside of the plant's leaf.
On flat vertical surfaces like plant leaves or aquarium glass
Most butterflies lay their eggs on plants: on the top or bottom of leaves, on the flowers, on twigs, in the chinks of bark, or on the plant stalk. Some butterflies lay their eggs near the plant: on dry grass stems, dead leaves, or on soil. By laying their eggs on or near plants, the newly hatched caterpillars will have something to eat.
A sawfly larva eats plant leaves and stems in its larva stage. The adult female sawfly uses her incisors to cut into the plant leaves and stems before laying eggs in the incision.
Plant hoppers typically come from eggs laid by adult female plant hoppers on plant stems or leaves. Once the eggs hatch, the nymphs emerge and feed on plant sap, eventually developing into adults. Plant hoppers are commonly found in agricultural fields and gardens.
The Sundew - is a carnivorous plant. It feeds on insects by trapping them using sticky drops of fluid on its leaves.
Monarch butterflies lay their eggs on milkweed plants. The milkweed plant is the only food source for monarch caterpillars, so this is where the female butterflies choose to lay their eggs.
on leaves
They don't hurt the milkweed plant, really. They do drink the nectar in the flower and/or lay eggs underneath the leaves of the plant.

Leaves are mainly responsible for photosynthesis in a plant.
A plant without leaves is called a "leafless plant."
