During a routine inspection, officials discovered over 30 live beetles, each almost the size of an average human hand, at a Southern California airport, as reported on Wednesday by federal authorities.

U.S. Customs and Border Protection (CBP) announced that agriculture specialists at Los Angeles International Airport uncovered 37 large beetles hidden within various packages of Japanese snacks, including potato chips and chocolate.

This contraband, worth $1,480, was identified during a physical check of a shipment arriving from Japan via air freight last month.

The release indicated that the beetles ranged in size from four to five inches long.

“They may appear harmless, but smuggled beetles represent a serious threat to essential agricultural resources,” said Cheryl M. Davies, the Los Angeles CBP Director of Field Operations, in the release. “Beetles can cause significant damage by feeding on plants, leaves, and roots, as well as laying eggs on tree bark, harming our forests.”

The illegal trade of exotic insects, which can be found for sale online, yields substantial profits for individuals who choose to disregard U.S. laws and regulations, the release noted.

In order to import live insects into the U.S., a permit from the USDA Animal and Plant Inspection Service (APHIS) Plant Protection and Quarantine (PPQ) is necessary, along with a letter from the PPQ’s Plants, Pathogens and Biocontrol unit.

Customs: Large beetles discovered on plane may be given to zoos

“CBP agriculture specialists utilize their expertise in harmful pests and plant diseases, along with their skills in detecting and intercepting these dangers before they reach our country,” stated Andrew H. Douglas, the CBP LAX Port Director. The beetles were handed over to officials from the United States Department of Agriculture, according to the CBP release. The agency will decide what will happen to the insects.

As reported by the CBP, it is likely that the beetles will be donated to local zoos that possess the necessary permits to care for them.
