I have a small crab apple, Robinson I planted last year. It looked ok this spring and had a few blooms even. Now the leaves are yellowing and dying off and I thought it just needed more water. We had a very wet summer up until the last 2 or 3 weeks and it turned hot. I noticed it looks like it has spots on it now. Does anyone know what this is or if I can save it? It also has this little thingy hanging on a branch (just one of them I found). I suspect it is a butterfly or something? Anyone know what it is and if it is friend or foe?
