Does anybody have any advice for the flying bug boss?

Last night my group got decimated in under 10 seconds by the difficulty 7 version of this boss. It went rabid and chased us down faster than we could hope to move and one tapped each of us, there was no chance at all, we were all left with our jaws on the floor as our run was shut down by one extremely fast extremely strong wasp. What’s the design concept on this guy anyways? Was it just a hate letter to the fans of this game? 🥲 in lower difficulties we could at least kill it quickly before it pulled this nonsense, but in difficulty 7 we genuinely don’t know what to do when the wasp goes rabid.
