What Are the Most Common Garden Insects That Eat Leaves?

Garden insects that eat leaves come in many forms, each with unique feeding habits and impacts on plants. Here are some of the most common offenders:

• Leafcutter Ants: These industrious insects cut and carry leaves back to their nests, where they use them to cultivate fungus, their primary food source.
• Caterpillars: The larvae of moths and butterflies, caterpillars can consume large quantities of foliage, often leading to significant damage.
• Aphids: These tiny pests suck the sap from leaves, causing wilting and stunted growth.
• Japanese Beetles: Known for their iridescent bodies, these beetles skeletonize leaves, leaving behind a lace-like appearance.
