Where does the walnut caterpillar moth typically deposit its eggs?

• A. On the surface of the soil
• B. Underside of leaves and pecans
• C. On tree trunks
• D. Inside the bark of trees

Answer: (B)

The walnut caterpillar moth deposits its eggs primarily on the underside of leaves and pecans. This behavior is advantageous for the caterpillars that will emerge, as it provides them with immediate access to food sources, specifically the leaves of walnut and pecan trees. By laying eggs on the undersides of leaves, the moth also protects the eggs from predators and environmental conditions, such as direct sunlight and rain, which could otherwise harm the developing larvae. This adaptation enhances the survival rate of the caterpillars after they hatch. Understanding this behavior is essential for those studying pest control, as it helps in identifying when and where to monitor for potential pest outbreaks effectively.
