Representative Chrissy Houlahan visited Braeloch Brewing in Kennett Square on Monday to highlight the damage done to businesses by the bug.
The spotted lanternfly likes "hops," a key ingredient in beer. And they like grapes, as well, which could have a big impact on wine production.
"When spotted lanternflies are feeding on grapevines, we are seeing a reduction in yield, we are seeing a reduction in fruit quality, and in some cases we are seeing complete vine death," said Houlahan.

Representative Houlahan is heading up a bipartisan effort to eradicate the invasive species.
Residents are reminded to squish spotted lanternflies to prevent them from spreading.
