We planted linden trees this year and wrapped the trunks with white corrugated tubing to prevent sun scald in the winter. In looking at leaf damage on the outside border of the leaves, I noted that there were literally hundreds of small gray/black flying insects clustered under the tree wrap. What might they be and are they responsible for the chewed leaves? What treatment is needed?



I'm not sure what the insect would be without more information. If it's possible, a picture would help of both the insects and the damage. I doubt they will kill the tree no matter what they are. It would also be helpful to remove the white tubing, if you haven't already. Re-apply the protection in the fall, and remove it in early spring each year. Instead of a tree wrap, you can also simply paint the trunk with white latex paint.
