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.

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:
