2 Insects on Butterfly Bush
One looks like granulars of sand in a drop of water. Shades of brown, light and dark. Crawls. Another looks like a crab, but elongated and is not an earwig. About one quarter inch, light gray, spins a web. One of the two leaves black droplets on leaves. One of them eats the leaves in circle and elongated pattern. One of them eats the tops of the plant/flowers not fully bloomed. One leaves orange, maybe eggs of some sort, on top by flowers/ stem.
