Bark Beetle
TL;DR
Bark beetles demonstrate aggregation pheromone signaling for coordinated attack.
Bark beetles demonstrate aggregation pheromone signaling for coordinated attack. When a beetle finds a suitable tree, it releases aggregation pheromones that attract hundreds of beetles to the same location. This coordination is essential because one beetle cannot overcome tree defenses, but 500 beetles can overwhelm them - demonstrating threshold-dependent collective action.
Notable Traits of Bark Beetle
- Aggregation pheromones
- Coordinated mass attack
- Threshold-dependent success
