What are the green droppings found on the ground near ivy?

The green droppings found on the ground near ivy are likely from caterpillars that feed on the leaves of the plant. Many species of caterpillars, particularly those of moths and butterflies, consume ivy leaves and produce droppings that match the color of the foliage. These droppings can also indicate the presence of other pests or wildlife that may be interacting with the ivy. It's a natural sign of feeding activity in the ecosystem.
