Haha you are right. Those don't look too scary. We have tarantula hawks here and it is super unnerving when they are flying around near you even if they don't sting often.
That is a pretty trippy weird cycle for sure. The one that trips me out is that fungus that infects ants and does something to their brain or whatever and drives them to climb up on leaves and wait until new fungus bursts out of their bodies like the freaking zenomorph from Alien or something.
