Oecanthus nigricornis


The shaded area shows the combined distribution of Oecanthus nigricornis and Oecanthus forbesi, two species that thus far are separable only on the basis of the calling songs of the males. Dots show county records of O. nigricornis that are based on tape-recorded males.

Computer-generated distribution map, produced in 2004 from records in a database available on this site. The records based on songs are O. nigricornis; those based on specimens only or on the literature are either O. nigricornis or O. forbesi.
