The mammoth wasp (Megascolia maculata) is a species of wasp belonging to the family Scoliidae in the order Hymenoptera. It is a parasitoid on scarab beetles and is found in Europe and Asia and is the largest wasp (not hornet) found in Europe. This insect does not attack humans, it is very peaceful.
the hornet was held down by the formica rufa/ wood ants also these guys are no joke their formic acid can dissolve insect internal organs and erode metal
