Hello Everyone! New here, found this forum 'cause I think here there will be more people with the right knowledge, than reddit or elsewhere on the net. On October 6th, 2017 in Waltham, Massachusetts, while sitting at the balcony, l saw what I think is a Lesser Angle-winged (Microcentrum retinerve) katydid and I decided to film it. I would like to ask You people, is it Lesser Angle-wing or Angle-wing Katydid (Microcentrum rhombifolium)? Also, on October 21st, 2017 at the same location I took a photo of another cricket that appears to be a Treetop Bush Katydid (Scudderia fasciata), according to one person from reddit who suggested it's this kind.

I think you should suffice it to say that the species is of the genus Microcentrum and be happy with that. There are right now 6000+ species of worldwide katydids (Tettigonidae) known to science and many more still to be discovered and named. The family is large; rivaling that of the entire Nymphalidae butterfly family (all subfamilies included). The number of credible professionals on this group is probably a small one. Literature with keys is probably tough to find. Perhaps some truly avid enthusiast of the group could take a stab at the species but, that still remains a guess unless you actually collected the specimen and keyed it out or had a taxonomist look at it.
Looking at a video is just is not good enough for answering a question at the species level (in most cases).

I'll keep both names how they currently are now, until someone with 99% certainty will claim otherwise.

It's safe to say that your Microcentrum is not retinerve, but rhobifolium as retinerve only gets as far north as New Jersey/Pennsylvania. As to the Scudderia, there may be a couple of species in your area, which are fasciata, curvicauda, furcata, pistillata, and septentrionalis. In that case, I would suggest you check out this link. entnemdept.ifas.ufl.edu/walker/buzz/katylist.htm#scudderia. SINA is a real good resource regarding orthoptera.

I've updated the title and description (changed it from retinerve Lesser-wing to rhombifolium Greater-wing). Thank You for the info!

I have been getting better with katydids as I help a good friend with his projects on shieldbacked katydids and cicadas. SINA is an amazing help as well as the Orthoptera Species Online. Great sources. If you need any more help, feel free to ask.
