Oak Tree - something engulfed tree

Asked June 4, 2020, 7:24 AM EDT

Hi, I've two oak trees that suddenly are under seige from some type of pest, fungus, or something. I've attached a picture of what tree has. One tree has no green leaves now, the other is 2/3 of leaves are gone. There appears to be some type of organism around where the leaves where. Looking for advise on what to do next. Thanks for your help, Rich Robinson

The leaves appear to have been consumed by insects. Although they may no longer be present, at this time of year cankerworms are likely suspects.
