Are these little eggs coming to life baby cabbage worms or something else?  |

Yep. About right of what I saw on my tree collards. Actually dried up this summer. Though I don't see the worm. Yellow eggs should be squished. Or soap water on the worms.

Cabbage butterflies lay yellow, spindle-shaped eggs.

Well I had previously thought the vacant patches on my leaves were from a form of leaf miner. I do get leaf miners at home and in the seedlings in trays. But now I think I was stupid and it was just the baby, real tiny, cabbage worms before they were making actual holes. Does this sound right? If so, no nematodes are needed, just more regular Bt.

Well now I was looking at photos that blew my mind. I didn't realize I had cabbage worms and cabbage loopers. I just thought that I had one. I have definitely seen the cabbage looper moths and OMG I was so unaware. I thought I knew more about bugs. I will say the cabbage looper moths are easier to kill than the cabbage worm moths. And it is the cabbage worms that are doing the little holes when young. I ran out of Bt this week for the season. I wonder if I need to spray anymore. Now I only have Spinosad.

That's a bummer Tamara, hope you can get it under control. Before I grew my own food, I used to get wigged out over holes in organic vegetables. But now I understand it's a sign of using organic practices. Now if I have to buy an organic vegetable in the store, I choose the one with holes!

I don't think the "stupid" part is right; but it does take a bit to know your enemy; if your planting isn't field-size, two- or three-day inspections may be adequate, squishing whatever eggs and larvae there are; the larvae seem to head for the tender, inner leaves. I tend to think that squishing the pests on the plant promotes the growth of critters that want to "eat" those pests.

A cabbage butterfly lands on top of a leaf and extends her abdomen around the edge of the leaf and deposits only one or two white eggs on the underside. They are usually no more than ΒΌ" in from the edge. Then she goes on to find another plant. That's why you often only find one or two worms per plant. There are none depicted in the OP's photo.

So those are baby loopers then?
