Question: something is eating the leaves on my plum tree?
Answer: Plum Aphids Aptly names, as plum leaves are the pests' favorite food. These aphids are green, yellow or brown and under ½ inch in length. They are found in curled foliage. The curled leaves then do not photosynthesize properly, which stunts the tree and/or fruit and, in severe cases, will kill the tree.
