Hey , While rearranging my beds I noticed that all the primrose Japonica that I moved had these tiny long white worms that looked millipede like except they are white.

They are not grubs , they are very thin and they do curl but when disturbed they start to crawl.

I have only found them on my primrose and I was wondering if This will kill the plant ? They are probably on the other primrose that I haven't moved because so far they have shown up on everyone I did move.

Please anyone know what this is ?

It looks just like a millipede but it is smaller and white.

Thanks

Laura
