Insects on Holly bush - beneficial or not?
There are about 15-20 bugs gathered in one spot on top of one of my holly bushes. They range from hues of orange to dull grayish. They've been there for several days now. I haven't removed them yet, because I want to know if they are beneficial or not. I know it's not that helpful w/o posting a photo, but does anyone know of any holly-loving insects that fit this description/behavior? I can't tell if they are doing any damage, but they appear to be plotting something as there are many of them but just in one tight group. Thanks in advance for any feedback!
