The females oviposit singly, 12 to 50 very small (1 mm) eggs near the midrib on the inner side of winter wheat and late spring grains. The eggs will hatch in 10 to 13 days to form wrinkled, hairy, humped back, yel- lowish larvae with dark brown legs and head that are usually covered with a glob of excrement (fe- cal matter). In about 2 weeks, larvae pupate in earthen cells in the top 2 inches of soil and emerge after 17 to 25 days as metallic, blue-black beetles about 1/6 inch long with a red thorax and red legs. This entire life cycle takes 45 to 47 days and the newly emerged beetles feed on grasses for a few days and enter summer diapause until fall when they hibernate under crop refuse in September and October.
