yes the moths they leave behind their young (eggs)to devour your unborn flowers when they turn into caterpillars.
I have the web worm moths mostly that come out of the grass in the yard.
but they leave behind eggs that will ruin your buds and flowers when they turn into feeders..(
the hawk moths are just huge and if they land on your plant they break them . not much you can do about that but why I put a bamboo stick in front of the buds and blooms on occasion. Keeps my arm from flinging around and breaking things too..
