Not illustrated. 1918 Excerpt: ... in the soil. They are similar to those of the June beetles, white, smooth and shining, nearly globular, grayish, and about inch in length when newly laid. They increase considerably in size before hatching, which takes place in one to three weeks. The larvae feed on the roots of grasses and decaying vegetable matter and sometimes attack the same plants as do the beetles. When mature, the larva is 1 inches in length, bluish white with the head brown. From six to eleven weeks are spent in the larval stage. The mature grubs construct earthen cells within which to pupate and the beetles emerge two or three weeks later. There is apparently only one generation annually. The measures suggested for the control of the carrot beetle are of little practical value. Clean farming and a short rotation of crops will under ordinary conditions prevent serious loss.
