The larvae live in the moist soil of meadows or cultivated fields, being most abundant in the soils of sandy texture. Pupation occurs during the early half of May, at from 5 to 10cm. below the soil surface. The pupal period lasts about 10 days. In structure, the larva is very similar to that of curatus (Candeze, 1873), but may be distinguished by the following characters : Head usually widest across middle ; frontoclypeal area widened posteriorly ; mandible with small retinaculum and usually with 4 or 5 fine denticles at base of retinaculum ; and has only slightly curved ungula ; abdominal mediotergites each with 10 prominent unpaired setae ; ninth abdominal segment about 1.2 times as long as wide, only 2 small setae on central dorsal area ; urogomphi strongly directed inwardly, frequently meeting at tips ; caudal notch broader than long. Length 6.5mm., width 1mm.
