Identification:  A long conehead with a modest cone that is immaculate and straight beneath. Lower margins of hind femur not darker near bases of spines. Male pronotal length greater than 1.8 times rear width; ovipositor shorter than hind femur. Length 52-61 mm for males, 62-67 for females.

Habitat:  Undergrowth of pine and hardwood forests.

Season:  First egg-overwintering conehead to sing in the summer: June–July; N. Fla. data.

Song:  A piercing, continuous buzz.

Song data:  Excel worksheet and chart (from spectrographic analyses).

Similar Species:  N. palustris is smaller and matures later in the year; in profile, its cone is concave beneath; lower margins of hind femur darker near bases of spines. In N. robustus and N. bivocatus the length of the male pronotum is less than 1.8 times its rear width. the ovipositor is as long as or longer than hind femur, and adults occur later in the year.
