Originally, the Japanese beetle is natively found in southeast Asia, but that’s hardly the only place it lives. In the United States and Canada, it has been an invasive species since 1916. Researchers believe that a shipment of iris bulbs contained the larvae of the beetles at the time, ...
The Japanese beetle (JB; Popillia japonica) is a scarab beetle introduced in New Jersey from Japan sometime before 1916. It has since spread to most of the country east of the Mississippi River and into Canada: populations are also established in Pacific coast areas. The beetles were also in...
Japanese beetles were first found in North America in 1916, near Riverton, New Jersey. The manner by which the species was inadvertently transported from its native Japan is not known; however, the grubs may have arrived in soil about the roots of nursery plants. It is considered a minor pe...
Females make a burrow of about 2 – 3 inches deep where it deposits eggs. Beetles that develop in the soil remain in the soil for about 10 months. These are white grubs. Grubs attain a full length (of about one inch) in August. White grubs mostly eat vegetable seedlings as well as r...
Japanese beetles are found in many parts of North America, particularly in the eastern half of the continent. If you don’t have this pest chewing on your plants, consider yourself lucky. These insects spend about 10 months of the year underground as white grubs that live in the soil in ...

These beetles have existed in Nova Scotia for nearly a century. But Debra Moreau, an entomologist in the Department of Agriculture and Agri-food Canada, says the population has only recently increased. Content continues below "I would say within the last 10 years, we've started to ...

2A). The beetles were observed using their mandibles to remove the coronal hoods (saccate extensions of staminal tissue in which nectar is stored) from individual flowers to expose the nectaries and other floral structures (Fig. 2B). Here we verify the extent of JB aggregation on milkweed ...
As larvae, Japanese beetles live underground, feeding on the roots of grasses and other garden plants. This often leads to brown spots of dead or dying grass in lawns—a tell-tale sign of a Japanese beetle larvae infestation. The adults like to feed on a variety of fruit and shade trees...
