New Spider Species Hunts Single Ant Type by Inverting Predator-Prey Dynamics

Researchers in Far North Queensland discovered a spider that deploys a spring-loaded silk trap calibrated to one prey species: the green ant, an aggressive insect that would overwhelm the spider in direct combat. Rather than a generalist web, the snare triggers on the ant's defensive behavior, launching it into the air with car-crash-level acceleration. The mechanism represents a radical departure from typical spider hunting strategies and a evolutionary bet that protein-rich green ants justify the energetic cost of maintaining a specialized trap.
