I have been wondering about this. Any ecologists or entomologists on the board? I think it's safe to assume that paving streets and building structures removes their habitat and reduces their numbers, but what's the ideal cicada habitat? Is it dense forest? Or do they prefer more open, meadow-tree boundary zones? I haven't had a chance to go out for a hike or anything... what are they like in the woods? They seem to do just fine in the mostly tree-covered suburbs. Do they do better with specific trees? So many cicada questions, so little time
