Thud Bug
this species of flying insect was bio-engineered from the sparkbee, which was once native to Yuuzhan'tar, the homeworld of the Yuuzhan Vong. The warriors used the flying bugs, known as nang hul, as projectile weapons, often imbedding them in their flesh or armor for use in battle. The silver-carapaced thud bugs could inflict simply physical trauma, or they could be modified to carry explosives which detonated on contact. In flight, a thuhd bug could reach speeds over 150 kilometers per hour. After the hostilities between the Yuuzhan Vong and the Galactic Alliance were resolved, and the Yuuzhan Vong were allowed to live on the planet Zonama Sekot, they found that thud bugs and many other bio-engineered weapons simply reverted to their animal forms and fled into the forests. This was one way in which Sekot forced the Yuuzhan Vong to give up their lust for war and embrace a more enlightened existence.
