Why Are There Butterflies All Over the Jersey Shore?
You’ve heard everybody talking about it and you’ve seen it all over your news feed on Facebook. “There are butterflies everywhere!” But, why?
They’re Red Admiral butterflies, although they at first glance do look like the Monarch butterfly. And if you’re seeing multitudes, it’s because it’s hatching season. That, combined with migration taking place is causing the creatures to be all over the Jersey Shore.
The sudden influx of the butterflies is called an “irruption” — a natural, cyclical population boom that causes an increase of butterflies every few years. And the unusually warm winter we had this year helped them to thrive, experts say. A boom of this size has not been seen in 12 years.
