The Japanese Beetle I refer to is Popilio japonica, obviously not the same
as the Japanese Laquer Beetle Ian describes. The larvae of our Japanese
Beetle feed on grass roots underground, only the adults are destructive
(very!) to a wide variety of plant leaves and flowers.
They love grape leaves and as soon as I did away with my grape vines, they
descended on many other plants in the garden.
Curiously, they bother only one iris--Iris virginica, feeding on the outer
halves of the leaves.
They can supposedly be controlled by pheromone trapping and by spreading
spores of a bacterium fatal to the larvae on the lawn. Since the adults
are good fliers control is hard to acheive if others in the neighborhood
don't cooperate.
Best wishes, Bill
