In order to camouflage them from predators, walking sticks tend to lay their eggs on the bottom of leaves or stems. They also lay them one by one so that they resemble tiny seeds instead of putting them in one large pile.
The answer is no, because, on the top of a leaf there is the, cuticle, then the upper epidermis cells underneath, which you can see these, because you can see a sort of jigzaw pattern on the top of the leaf. but on the bottom of a leaf there are tiny, guard cells, a guard cell is a cell that lets in carbon dioxide to the leaf, but only on the bottom of the leaf. if you have ever wondered why a leaf is greener on the top, than the bottom of a leaf, is because, sunlight can easily reach the top of a leaf, this is called photosynthesis, but on the bottom of a leaf, it only gets sunlight from refections from the ground, because the bottom of the leaf does not have any visible contact with the sun.

Most butterflies lay their eggs on plants that will be eaten by the caterpillar, when it hatches. Some species lay their eggs on the tops of leafs, some on the bottom, some at the leaf axils, some on flowers, and some on stalks. Which species do which is not known in all cases.
Wrong, a spiny leaf insects droppings is not its eggs there is an obvious difference the eggs are round with a white stripe and have a small cap on the top.
