Butterfly Bonanza: Red Admirals Swarm to NJ

Red Admiral butterflies are calling NJ home for the time being. Mike Crewe, program director with the Cape May Bird Observator, says that ‘because some ecological switch got flicked somewhere, Red Admiral butterflies apparently decided to leave the warmer confines of the South and migrate north,’ the Asbury Park Press reports.


“Every single butterfly is flying due north,” said Crewe, who spoke recently with a specialist in butterfly migrations. “He said this is the biggest movement he has ever seen, which tells me something.”

A change in temperatures or in the length of day likely served as the basis for the migrationary trigger, Crewe said. It’s unclear how much longer the immigrants fluttering outside will last. Stay tuned!
