Japanese Beetle

From Bugwoodwiki

Japanese beetles are broadly oval, 12 mm long, metallic green and coppery, with small tufts of white hair both behind and on each side of the elytra (fig. 10). Prevalent in some Atlantic Coast States, they emerge from May to July and live for 30 to 45 days. They feed on over 300 plant species and devour sycamore leaf tissue between the veins, commonly leaving only a lacelike network of veins. They may completely defoliate seedlings and young trees. A milky disease bacterium, Bacillus popilliae Dutky, is commercially available to control the larval stage in the soil. Chemical control of adults may be needed.
