Boston area peeps: Now is a great time to get rid of that Ailanthus tree that you've been meaning to cut down.
The spotted lanternflies are arriving and they're going to turn the area under that tree into a black, sticky/slimy mess. The lanternflies just *adore* Ailanthus, and as they feed on it, they poop out sugary sap onto everything below. Some kind of black fungus then goes nuts over it.
(They eat other stuff too but it's not as intense. And Ailanthus is itself invasive.)
