In 1916, these islanders were already settled in New Jersey, meaning they had already traveled across the United States.

So, where do Japanese Beetles Go at Night?

After a tough day at work, Japanese beetles go to their underground nests as people go to bed.

From late spring until mid-August, they like spending warm days outside and moving around before searching for their nest at dusk. The Northern Masked Chafers are perhaps the only beetle still feeding at night during this season.

When Do Japanese Beetles Come Out?

The Japanese beetles typically emerge at 9 am and remain active until 3 pm, when they become less active and head back to their nests. To put it another way, they prefer to feed and travel during the day, which is why you hardly ever see them at night.

If you’re unsure of the location, Japanese beetles spend their nights. The answer is that they make their own nests to rest.

They like to be outdoors on sunny days, between mid-July and late August.

If you find night-feeding insects during this time, they’re likely northern masked beetles with an activity pattern similar to the seasonal like the Japanese beetle. However, they are not nocturnal.
