Ant bugs like this one lie in wait on tree bark near foraging
ants. When hungry, they rear up and expose their undersides, which
release a secretion attractive to ants. As the ants start feeding
on the substance, they become lethargic from a narcotic in the
secretion. That's when the ant bug strikes, savagely driving its
beak into the weakened ant's body and sucking out its life juices.
The ant bug's hairs protect it from any death-throe bites or
scrabbles by its victim. Today, ant bugs are extinct in the
Western Hemisphere.
