I think I like the assassin bug a little bit less after watching this video which shows how it uses its "rostrom": http://www.sciencechannel.com/tv-shows/monster-bug-wars/videos/monster-bug-wars-assassin-bug/ (You can see the rostrom on this nymph, who is spending day three since its discovery, below the sunflower bud it was parked on, because the bud is opening.)
