Eggs – good or bad?

Painted lady or DBM eggs?

Any ideas what these yellow spheres on my snapdragons might be? ~1mm, not usually in clusters, mostly scattered and only seems to be on my snapdragon buds/flowers.. not sure if I should leave them be? I’ve noticed a number of painted ladies in the garden and google seems to show that these look similar to the eggs but I’m not 100% sure..

Having a mini diamondback moth epidemic (think 100s) here at the moment so I’m kinda overwhelmed. I looked up diamondback moth eggs and while they look similar they’re mostly under leaves and in clusters (I’m assuming picture 4’s DBM eggs?).

Noticed some smaller brown caterpillars too which looked different from the moth caterpillars (green).
