How terrorists could use insects for weapons

Interesting article (though no mention of scorpions). Also, from the article, I didn't know this:

Armies have long used bugs to spread disease among their enemies. The Black Death arrived in Europe after the Mongols catapulted flea-ridden corpses into the city of Kaffa on the Black Sea...Those who fled from the city brought with them bubonic plague, which killed 75 million people in the 14th century.
