Hello everyone. We noticed one of our young tree having problems a few days ago. All the leaves are burnt/dead. It was doing so great before that. I just went to check on it and noticed all those bugs crawling up and down the tree. Can you please help me identify them? We have 2 cypresses next to that tree that don't look good either. So I'm afraid we have an infestation of something.

Sorry it's getting dark outside and I had to zoom a lot.

Thanks
Stephane
