|These carnivorous insects are easily recognized by their long, spindly legs and compact bodies. When hunting, a yarzon first seeks to immobilize its prey by spraying its joints with a stream of corrosive bile. Having done so, the vilekin then penetrates the victim's cranial cavity with its dagger-sharp feeding rube and sucks out the brain. Species of the yarzon can be found thriving in both humid marshes and arid badlands around Eorzea- a testament to the creature's impressive adaptability. 
Fiercely territorial, these creatures will attack anyone who strays too close to their riverbank nests, making them the bane of fisherfolk. They typically fall upon their prey en masse, barring all avenues of escape before closing in for the kill.
