What eggs?
It would be nice to know what eggs these are and to move them to the corresponding page, even if we don't get them down to species.

I updated the image to include that, sorry for any confusion.

 
They are identified on the first image
as Microcentrum rhombifolium. I think it makes sense to file these under the parasitoid, since the exit hole shown is a sign of the parasitoid, but we could put a thumbnail of this image on the guide page for the katydid.

 
exit hole
I am wondering how one can tell the difference between the hole from a parasitizing wasp entry and the hole the katydid emerges from. I've been fortunate enough to witness the emergence of a katydid from an egg. I saved a sample to take in to work (garden maintenance company) and by sheer coincidence, I happened to be there with our resident expert and a microscope that took video of it after we realized what was happening. I always assumed when I found the eggs with holes in them that they were emergence holes and not from parasitizing wasps. Is that incorrect? I don't actually remember what the egg looked like after we watched it come out because we were too fascinated by the process.

 
Exit holes
Little round exit holes in katydid eggs will always indicate parasitoid wasps. When katydid nymphs emerge, they split the egg like so:

 
Thank you so much!! I will p
Thank you so much!! I will pass this info along to my fellow gardeners because I think we all assumed incorrectly.

 
Yes
Either that or another image of the eggs on the katydid page. I wonder why they seem covered by cobweb.
Now that I looked at other eggs I see a similar hole here:
