Today I just noticed that some of my seedlings are starting to get tiny white specks on their leaves, and a quick look underneath them revealed some tiny white/yellow cocoon-like things.
My suspicions led me to believe that these two things are linked, but what are these cocoons and how do I get rid of them? For now I've just checked under every single leaf of all my seedlings and scraped them away with my nails. Is there an easier, less painstaking way?

The white round things look like eggs -- I want to say butterfly.
(what is this plant?)

What were the greenish things near your thumb? They look like they could be sucking insects like aphids, but they are too blurry for me to tell for sure.

All of the things under the leaves are the same eggy things. They're not really round, they're more long.
The plant in itself I can't quite remember, I didn't label my seedlings this time D: Which I regret. Although I'm fairly sure they're Stock, because I know what all the other seedling's of the other flowers I planted look like.

So, I looked up Australian butterflies that might use stock as larval host plants. I was looking forward to discovering something exotic....

According to this website, only one instance of stock as larval host is listed

Much to my disappointment, it's Cabbage White! -- common butterflies that usually lay eggs on cabbages, broccoli, etc. that hatch into velvety green caterpillars.

Funny thing is I actually thought those eggs look like cabbage white eggs, especially late in the season when they are in "dump" mode (particularly when you said they are not round but oval)... but thought that couldn't be possible because this plant didnt look like a cabbage family plant.

Bah, that makes sense. I remember seeing a bunch of them floating around not long ago. They must be missing the couple of cabbages that we just had to toss because they were snail-ravaged.
Interesting web page there though, definitely one for the bookmarks!
Ta for your help

looks a whole lot like whitefly eggs

Gah, I've seen a lot of those around too!
It could be either of them.

I don't think the eggs are whitefly eggs -- they are too big.
BUT I was thinking we didn't address the white spots (cabbage whites butterflies would not have caused the white spots) and they do look like signs of whitefly.

I think the pure white long thin thing on the leaf to the bottom left next to the one you are folding over to show those eggs LOOKS like a whitefly.

Can you tell me what the name of that plant is. I had something that looks like that pop up in my yard last year. It puts out a bracket with tiny flowers that turn into tiny berries. It's really something to see. I would love to figure out what it is.

Those pics above are the ones in my garden. If anyone recognizes them I would love to hear what they are.
