Hahaha!! We have a crabapple that was oozing sap this fall. I was cutting lower branches and noticed I wasn't alone!! The trunk was covered in European yellow hornets!!!! An invasive species. I've been stung before by these, they are no joke!!! There were also bald face hornets lower down on the trunk. I watched as one of the bald face hornets sgot too close and a yellow beat her up!!!! These bald face hornets are wicked in there own right!!! But only half the size of the yellow giants. I slowly backed out and got out from under that tree!!! Leave those mean girls alone!!!
