Hi Tom

I'm very familiar with the species of cicadas in Massachusetts and all of New England. We do not have T. robinsonianus here in Massachusetts. This is way too far north for that species. Especially in Groton which is the next town over from where I live. This specimen is actually T. canicularis. They do vary morphologically which makes them difficult to identify if you are not familiar with the species. The two most common species of cicadas we have here in Massachusetts are T. canicularis and T. lyricen. We have isolated pockets of T. chloromerus on the mainland of Mass but as far as Tibicens go, that's it.

I have managed to find large populations of T. chloromerus on Nantucket Island and there is a healthy population of T. auletes on Martha's Vineyard. I have also found Okanagana rimosa in Central Massachusetts.

Hope this helps.
