Remarks and Distribution. The geographical range of this widespread species extends from eastern North America south to Florida and Louisiana and across Canada to Alaska ( Earle 2009, Nelson 2000, Stewart & Oswood 2006). Mature larvae of this species can be separated from others based on the lack of abdominal projections ( Figs. 28 View Fig , 36 View Fig ), supraantennal plate developed into a semi-circular ridge ( Fig. 30 View Fig ), the presence of a convex lateral bulge on the pronotum that often exceeds the level of pronotal projections ( Figs. 32 View Fig 32-34 , 36 View Fig ), and a broadly rectangular process on sternum 9 of male larvae, the resulting angle=33.11 ± 5.16 ( Figs. 29 View Fig , 35 View Fig ).
