PHILADELPHIA (CBS) — Philadelphia police have issued a public service announcement: Please do not contact authorities if you see a Spotted Lanternfly. Instead, the department said on Twitter that the insects are not a police issue and Philly should welcome “our new insect overlords.”

“Please do NOT call 911 to report #SpottedLanternfly sightings,” the police department wrote in a tweet. “While they are a nuisance, they are not a police issue. And on that note, we, for one, would like to welcome our new insect overlords. Maybe they would like to build some nests on our vast concrete headquarters.”

Spotted lanternflies have invaded the Delaware Valley this summer, destroying trees, crops and even leaving behind a foul-smelling sticky, tar-like substance.

The insects, while native to Asia, were first spotted in Pennsylvania in Berks County but has since spread into southeastern Pennsylvania — including at Ridley Creek State Park in Delaware County.

“It’s not a good smell,” Ridley Creek State Park Manager Phillip Schmidt told CBS3 in August. ” We call it ‘dew,’ and if you stand under this tree right now, it seems like it’s raining. It’s the dew coming out of them.”
