A pest never before seen in the U.S. has been found in a shipment of fresh pineapples.

The pest, Acrogonia nigriceps, was found Aug. 24 by U.S. Customs and Border Protection officials in Los Angeles in a container of pineapples from Costa Rica, according to a news release from the U.S. Department of Homeland Security.

On Aug. 26, U.S. Department of Agriculture entomologists identified it as Acrogonia nigriceps, a member of the Cicadellidae, or “leafhopper,” family.

The pest can cause significant damage to grapes, potatoes and other crops.
