“Deadly 60”, a kids TV show here in the UK, once showed a desert spider that spun a loose web on the sand, making a sand-blanket, then backflipped it over its head and hid under it like a sniper in a ghillie suit. It then waited for an ant to go by, grabbed it by leg, and held it down on the sand until it cooked it to death. Antlions are still cool though.
