I live in the D/FW area, and I'm growing a Mt. Hood vine that's doing
fine, except that some sort of insect is making a feast of the leaves-
eating holes in the middle and from the outside also. I've been
dusting them with Schultz Garden Safe pyrethrin dust, but I'm not so
sure it's working- it's hard to keep on since it's been raining a lot
lately.

The only insects I've seen near them are these little green/black
metallic looking bugs that I can't identify.

None of the hop growing sites I've looked at mention any sort of
leaf-eating bugs, so I'm not sure what the right course of action is.
Anyone have any ideas?
