Male Red Wasp head butts a female (worker) Southern Yellowjacket so hard you can hear the Yellowjacket hit the ground. This is an excerpt from a longer video of various wasps feeding on Fatsia flowers. There is quite a bit of competition for the nectar resource, and many of the wasps are male and have nothing better to do before they die. My YouTube channel is Bird Nird, and I’ll be uploading more wasp videos there
