 family. Accidentally imported to the United States from Japan, it was first discovered in New Jersey in 1916 and is now widespread in the northeastern states, where it is a serious pest of lawns, orchards, and gardens. The adult is about 1-2 in. (13 mm) long with a metallic-green head and thorax and reddish-brown wing covers. Metamorphosis is complete (see insectinsect,
invertebrate animal of the class Insecta of the phylum Arthropoda. Like other arthropods, an insect has a hard outer covering, or exoskeleton, a segmented body, and jointed legs. Adult insects typically have wings and are the only flying invertebrates.

). The eggs are laid in the ground; the small white larvae, called grubs, feed on the roots of grasses, sometimes killing them, and hibernate during the winter. Pupation occurs in the spring, and the adult emerges in midsummer, feeding on and destroying leaves, flowers, and fruits. Many methods of control have been tried, especially those involving the insect's natural enemies—e.g., parasitic wasps and flies, some of them imported from Japan; bacteria that cause the "milky disease" of grubs; and certain parasitic nematodes. None, however, have been entirely successful in controlling the spread of the beetle. Japanese beetles are classified in the phylum ArthropodaArthropoda
[Gr.,=jointed feet], largest and most diverse animal phylum. The arthropods include crustaceans, insects, centipedes, millipedes, spiders, scorpions, and the extinct trilobites.

For example, Japanese beetles and other beetles are associated with areas of managed cool-season turfgrass (Potter and Held, 2002; Hamilton et al., 2007), suggesting that laughing gulls likely were foraging in parks, residential lawns or potentially on the JFKIA airfield.
Herbivory by Japanese beetle larvae and endophyte infection both had a significant influence on response parameters of perennial ryegrass growing in mixtures with dandelion (F = 14.9; df = 3, 25; P < 0.0001, and F = 8.6; df = 3, 25; P = 0.0004, respectively), but there was no significant interaction between herbivory and endophyte infection (F = 0.38; df = 3, 25; P = 0.77).
