what is this on my thuja green giants? Eggs? aphids? ???

atlfuzzy1September 23, 2012

Hello there,

I have some visually flourishing thuja green giants (arborvitae) and over the summer have noticed branches with some grey/blackish dots on the tips......i can't see that they are moving, just don't know what they are.

There might have been a cluster of the same on the siding of my house...can't decipher if they are the same.

But more worried about the trees.

Thanks for any input!

anyone have a clue? Went to local county extension office and they had no idea, said they couldn't tell until the eggs hatched.

We usually don't answer if we don't know, lol. At least, that's MY excuse. Someone else posted a picture of these same things on this same plant in another forum and no one could solve it there, either.

I can only suggest putting them in a clear jar and wait to see what happens.

i figured you would suggest a late laying stinkbug .. confused as to what plant they were laying on .. based on the uniformity of the pattern.. subject to the leaf shape ... or one of those other bugs that usually use the gourd family ...

you know.. momma bursting at the seams.. man.. when the time come.. they gotta come out.. wherever she is.. lol ...

regardless.. if that is the sum total of what you found.. i would ignore it ...

if the plant is covered in them.. then i might react ... but frankly.. eggs dont even mean that bug will have any impact on that plant ...

you might want to take such to your extension office.. or a high end nursery.. the local peeps might know .... or be aware of ... what plague is currently in your area ... and if in fact.. it is a problem ... be leery of them wanting to sell you remedies ... come back and discuss with us first ...

Jean is here. But I can hardly see the "things." (I don't like to guess.)
