What are they? Do they cause damage to your plants?

They are moths, they are here to lay eggs under or on the leaves. At this stage they do not harm the plants but when the eggs hatched, the caterpillars will eat up all the leaves of the dr plants.

Koi,

So what do you do about the eggs/caterpillars?

It is obvious, I removed the eggs to other shrubs far away, take no chances for my dr.

Of course it's obvious that the eggs have to be removed...just wondered how you dealt with the problem.

Hi Chris, this is how the moth or butterfly eggs look like.

when they reached this stage, it is disaster.

Oh, then I ve watch out in future before it turn into caterpillar.

it is a type of sphinx moth. they should feed on other plants too. you could put them in an aquarium and feed them leaves to watch the life cycle. need a screened in top.
