Hello, My hedge maple tree is infested with these black insects on the under side of leaves , especially the leaves at the tip of each branch. Some of these insects have long clear wings while others don't. In some instances, the leaves are curled up with gluey substance, likely released by these nasty creatures. When I uncurled these leaves, I see more black insects, eggs and in one instance long green larvae. Some shiny spots on the leaves as well. Can anyone please help me identify and control these bugs??
