PHILADELPHIA (AP) — Customs agents seized more than 2 dozen giant beetles — some the size of a child's hand — from an overseas package after postal workers heard the insects making scratching noises.

The large bugs arrived last week from Taiwan at a post office in Mohnton, about 50 miles northwest of Philadelphia, in a box whose contents were labeled as toys, gifts and jellies, officials said Wednesday.

"The specimens were some of the largest of their kind and some of the largest I've ever seen, averaging 5 to 6 inches in diameter," John Plummer, an agency agriculture specialist, said in a statement Wednesday. "They are highly destructive insect pests that can cause extensive damage to fruit and vegetable crops, trees, shrubs and turf grasses."
