June Bug

June Bug The Green June beetle is 15 to 22 mm long with dull, metallic green wings. Its head, legs, and underside are shiny green, and its sides are brownish yellow. The green June beetle occurs in the eastern United States westward to Kansas and Texas. Green June beetles prefer ripening fruits of many plants. The grubs feed on decaying organic matter in the thatch and root zone of many grasses, as well as on the underground portions of other plants such as sweet potatoes and carrots.

Both the June Bug and the Japanese Beetle can cause damage to roots in their larval stage under ground. They overwinter as grubs that may become active on warm winter days.  Information provided by http://www.ces.ncsu.edu/gaston/Pests/junebug.html#home.

Treatment for the grubs is best applied in August to mid-September.
