You have probably noticed the Japanese Beatles feasting on your trees, shrubs, and flowers, but what you might not realize is they are also mating and laying eggs in your soil and turf. We are now in stage 5 of their life span which takes place from July to September as they begin to lay up to 60 eggs.
Stage 1: A dormant grub burrows deep into the soil from October to March
Stage 2: When things start to warm up in March and April the grub starts to feed on roots.
Stage 3: The grub pupates and turns into an adult Japanese Beetle after the spring feed between April and June, and only after its third summer of its life cycle.
Stage 4: The adult Japanese Beetle emerges from the soil to feed on different plants during the months of June, July, and August.
Stage 5: While continuing to feast in July, they also begin mating and laying eggs in the soil through September.
Stage 6: These eggs then hatch into grubs from August to October before going dormant to repeat the process over again in the spring.
