Unlike the wheat wireworm, this wireworm matures in May. The change to a pupa takes place in little earthen cells in the soil. We have not seen the pupa; this stage lasts about three weeks. Most of the beetles emerged In our cages in June. In Professor Forbes' experiments in Illinois they emerged as early as May 25th. f The beetle varies from 9 mm. to 15 mm- in length, and is of a shining black- ish color with brown legs.
