The eggs I found were white and tiny, very easy to miss. For what it's worth here is a picture of the eggs. They are laid in small clusters, spread in multiple spots on the leaf. You can scratch the eggs off with your nail if you can find them. I found most on the underside, but some were on the top.

This shows some of the leaf miner damage. The larvae / worm eats out the middle of the leaf and it protected by a thin layer of leaf "skin" on the top and bottom. You can squish the worms or rip out the affected spots.
