Moved from Tibicen resonans.

Although T. auletes and T. resonans are sister species with several overlapping characters including similar sounding songs, they are very different - and T. auletes is by far the largest of all North American Tibicen species.

NOTE: T. auletes is typically pea-green to olive-drab (rare red morphs can occur), however, it is the pruinosity, white powdered appearance, and heavy greyish-white frosting across the thorax and heavy white banding of the abdomen that is absolutely characteristic of this species (T. auletes) and no other in the continental US!

With regards "to the mm measurements", there is tremendous variability in size from individual to individual within all taxa, and exact measurements are good guidelines, but not absolute for id.

Please refer and compare the images here with both T. resonans & those on the T. auletes node - these images are absolutely congruent with the many others under T. auletes.
