These tiny 2 mm Treehoppers are of the group that imitates caterpillar droppings. When hidden in the branches with their legs tucked in, they look exactly like larval pellets. These were very actively creating large masses of white eggs on the surfaces of the branches. A spiny nymph is visible in the third picture. Adults are a dark chocolate color with scattered light brown spots and a white spot in the rear. They are surprisingly hairy. The tarsi are also light brown. Family Membracidae.
