Tiny Green Balls Appeared next to my Onion

[joles]

So, I have netted my raised garden bed because of several pest issues, but a storm started a couple days ago, and when I woke up today to check things, the net was gone, and my onion plant was not only chewed up, but also had these tiny dark green spheres lying around the base. It's still storming, so I'll try to get pictures once it's calmed down a bit.

Please note, I made the soil for my bed, I have never put any fertilizer other than manure or worm compost that I also make myself. I just transplanted the onion a few weeks ago, because I was keeping it in a pot (due to the constant attacks on my raised garden bed).

I'm still trying to learn why the pests are so interested in my raised bed, since they rarely touch my in-ground garden area, but I can't find anything online about what this might be. Please help!

These are the balls. Are they part of the onion plant itself? Or seeds? I've never seen onion seeds like this before...

Just had a word with @zigs and he says it may well be frass - in other words poop that the leek moth caterpillars have left behind. They do lots of munching and that looks like the result,

I've never seen that before either. It does look like poo that's turned green from the onion stalk itself. They must have really been munching away for that to be. Sneak out there and see if you see something.

It can be green or brown I think, but the green poop looks posher

Yep, looks like the leaves have been eaten, I've seen green poo like that when Cabbage White cattterpillars have been munching away on my Broccoli
