Small green spores(?) on trees

Hi there,

I'm relatively new to bonsai and have been given a half dozen trees of mixed varieties (and stages of "doneness") as a gift from a more experience bonsai-er. Anywho, they're away for a while and I've come up with a few questions that I don't seem to be able to find answers for with simple google searches or hunts of the forums.

First one I'll post here, the other is more of a care related question so I may post that elsewhere instead.

I recently noticed that a few of the trees (including an Eastern White Cedar - Thuja occidentalis, and some kind of juniper for which I'm unsure of the species, but it might be Juniperus chinensis) have a tiny green spore-ish like growth on some of the leaves. It's a tiny green pod on a long thin filament and it sticks straight off the leaf or branch bit it's growing on. I'll include some pictures, but mostly I'm trying to identify what the growth is and if it's harmful and any specific treatment instructions that might accompany it.





Thanks!

Looks like they could be lacewing eggs...see google images of lacewing eggs If this is what it is, it's a good thing, as lacewing larva are predators.

Not sure if other insects deposit their eggs this way.

Side note...I saw one of the larva (you can google that as well) on one of my plants the other day, didn't know what it was but it looked like something that would eat other bugs. Now I know!

I wish you'd indicate what we're supposed to be seeing. These old eyes don't see anything unusual in those -- somewhat blurry -- photos. A little red arrow will help.

I had a tough time finding them, but believe this is what he is referring to (inside red circles):

Yes coh the spots in the circles are what I'm talking about. Sorry Jim that I didn't indicate the objects more clearly.

They do indeed look very much like the pictures you linked for lacewing eggs though mine are a pale green colour. Seeing as these appear to be beneficial I'll just keep an eye on them and see what happens. Perhaps they'll help as well with some of the scale infesting some of my segregated trees too. <fingers crossed>

Thanks!

Sorry I have nothing to add other then my fascination for those cool eggs. What a neat way to lay them.

Everything has a purpose. Lacewings lay their eggs on these little stalks because if they were just laid on a branch, the larvae would eat each other as soon as they hatched. This way they get a chance to disperse & look for other prey.
