: Japanese Beetle on a milkweed plant

: A cluster of Japanese Beetles

: Japanese Beetle with four eggs from a parasitic fly called a tachinid fly. Leaving such beetles alone is advisable because it may lead to additional tachinid flies that can go on to parasitize additional beetles (such parasitism typically kills the beetle).
