Somchai Rice Ph.D

Japanese beetles (Popillia japonica) made their way into the US around 1916, probably from larvae hitching a ride in the soil of imported plants.  Female beetles burrow 1 to 4 inches below the ground level to lay their eggs (hatch in 14 days).  The larvae live the entire winter, feeding on the roots of plants.  They are white grubs from August through the winter to June.  Adult beetles emerge from mid-June into mid- to late-July.  Read more about Japanese Beetle
