How did this happen?
Its altitude suggests that it was grabbed by an adult mantis, but since I have not seen this reported on extremis I guess there is more to it than that. Perhaps it happened in combination with jumping spider stun effect when it jumps? (Battle Arena, here I come!)
Full video here in case it is needed.
I was able to replicate in Battle Arena by putting 200-300 worker ants against 50 L mantis with 100 jumping spiders:
