Which of the following is NOT a natural predator of the Japanese beetle?

Lacewings are not natural predators of Japanese beetles. In fact, lacewings primarily feed on aphids and other soft-bodied insects during their larval stage, making them effective pest controllers for those specific types of pests. They do not have a significant role in controlling populations of Japanese beetles, which are a different type of pest altogether.

In contrast, skunks, crows, and moles can consume Japanese beetles as part of their diet. These animals are opportunistic feeders and will eat a variety of insects, including beetles. Understanding the roles of different species in controlling pest populations is essential for effective pest management and promoting ecological balance in gardens and agricultural settings.
