Pheromones (aura) 5 miles. Yaiafinetis communicate with others of their kind via airborne pheromones. They can use this form of communication to determine their relative distance to each other, call for help if they are under attack or need sustenance, announce that they've detected prey, and convey similar basic concepts. Pheromones coat everything within the aura and allow all dusk poppies to perceive with their pheromone sense.
