Is it possible to ID from the egg?

Found multiple eggs as seen above dotted singley here and there on the undersides of multiple leaves, after seeing what I presumed was a monarch butterfly flying out of my yard. The kicker is that I didn't get a close look at the adult. And I didn't know about the "Soldier" and "Queen". I have not found any pictures of their eggs so don't know if they look the same as the monarchs' eggs. I do know about the Viceroy but know that they don't lay their eggs on milkweed.

Since the eggs will be hatching anytime now, I'm expecting to make the definitive ID based on the caterpillar but am curious if the egg is enough to make a positive ID.
