Cicada dual emergence brings chaos to the food chain
The headline "Cicada dual emergence brings chaos to the food chain" sounds alarming, but the reality is more of a boom-and-bust situation for different parts of the ecosystem. Here's a breakdown:
Feast for Predators: Cicada emergences are typically a scheduled event, happening every few years for a specific brood. But a dual emergence, where two broods appear unexpectedly, creates a massive buffet for predators. Birds, squirrels, raccoons – anything that eats insects – enjoys a period of easy pickings.
-
Stress on Prey: However, this abundance can be disruptive. With so many cicadas available, predators might focus less on their usual prey, leading to a temporary population decline for other insects.
-
Restoring Balance: Eventually, the cicada population thins out again as they reproduce and die. The predator population adjusts back to normal, and the ecosystem finds a new balance.
