    Hello, we looked at your pictures and think that you have a weevil problem, specifically black vine or strawberry weevils.
    The black vine weevil is a small (1/3 inch) brownish black insect. Try spreading a dropcloth around your plants, then shaking the plants; the adults will drop and can be removed. Spray leaves several times with pyrethrin for major infestations. The small, curved, white grubs of these weevils feed on the roots; drench the soil around the base of the plant with a solution of parasitic nematodes for control. These measures should also help control the strawberry weevil. Hope that helps!

    Your rose is being harvested by an Alfalfa Bee. This pattern is caused by the leaf cutter action of the Bee collecting for it's nest. If you watch your leaves in the mid morning you will probably observe the small dark solitary bee cutting a leaf and rolling the piece into a tube and flying off. It is short term this time of year and will not hurt your rose - other than looks. I would suggest not using chemicals on these beneficial friends.
