Well, it depends how big the tree is. For most situations, just wait until it leafs out and prune off the dead parts just above a living lateral branch.

if the tree is quite small, however, it could potentially be disfigured permanently.

Got a pic to show us?

I am wondering when they will re-visit my yard. Southwestern Pa here. I remember them being here in the late to mid 90's. My red oak seedling was affected big time. It is now my neighbors red oak, quite large now. If I had to guess the ciccadas will be here in 2015-2016. There is a chance that 2014, (now) is their time also. But I doubt it. My memory isn't too great. I hope it isn't until 2016. I have many trees that need some girth in order to deal with ciccadas and fare well.

This is mainly for HairMetal4ever ...
Firstly, sorry I'm late in posting back. Your suggestion for a picture was a good one (and I almost uploaded one) but I really decided that I'd just "wait & see". Well, I'm happy to tell you that, at long last, the tree leafed out and looks pretty good. As with most of my trees/shrubs, the harsh winter we had pushed the schedule back about 3+ weeks. But beyond that, the cicada larvae really took a toll on some of my shrubs, especially the rhododendrons - the ends of many branches croaked and withered. But the rhodies are quite resilient and came back. As I said, the poor Kousa dogwood limbs & twigs looked really bad (some were bent almost 180ð) and it took forever to set buds. It finally leaved out and set a few flowers (I'd say about half of what it did the year before) but I'm grateful that it seems to have rebounded.

Poaky1 - I hope you don't have the mess we did w/ the cicadas. I remember that period - the incessant racket was surreal - like something out of a Stephen King movie! âº

They are due to come out any year now. I thought it was 1995 when they came here last, but 2012 should have been their last time then, well whatever, I am not looking for ward to that. I likely remembered the wrong year anyways.

Poaky, there's a timetable by county at the link below for PA.

We have some kind of yearly cicada down here, not as bad as the cyclical ones but they made a racket from early June until October, gosh I dislike them.
