I was wondering why the gall is sticky? Also, exactly how does the wasp create such an intricate structure ?

I would just leave them be. Unless they are all over the trees in high numbers it should not be a problem. They may have hatched out by now.

Thank you Wendy. There are some really interesting insects out there! I am always amazed how much we still don’t know about the natural world. For instance, I could find little to no info of the adult habits of this creature.

Happy Spring,
