Identification:  A south Florida conehead with a black-tipped cone slightly longer than wide and 0 or 1 spine on the anterior ventral carina of the middle femur. Length 47-62 mm.

Habitat:  Roadsides and fallow fields.

Season:  Sept.–Dec. (at least)

Song:  Medium-loud, continuous buzz.

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

Similar Species:  N. affinis has the anterior ventral carina of middle femur with 3 or 4 spines.

Remarks:  This species is found throughout the West Indies and apparently in Mexico, Central America, and northern South America. It was only recently discovered in Florida, where it occurs in agricultural areas (Walker and Whitesell 1978). These facts suggest that it is, like the Jamaican field cricket, a recent addition to the Florida fauna.
