The eggs then take only blood until ready to emerge from the egg sack. At that time, the maturing Tlic grub eats its way out of the egg casing. Once it emerges, the grub begins to excrete a poison which sickens the host. Soon thereafter, if not removed, the grub begins to eat its way out of the host, which quickly expires. At the emergent stage, the grubs are about 15 centimeters in length and boneless.
Most Tlic eggs produce females, though only one per clutch is usually fertile.
One or two males may emerge, which are highly prized. The males lead short lives and expire after mating. If the host is valued, a Tlic may use its narcotic stinger to anaesthetize the host, its sharp claws to open the body cavity, and it's congealing saliva to slow bleeding. The grubs can then be removed and placed into a lessvalued carcass before they consume the original host. Terrans are especially prized as hosts, and may possibly host three clutches of Tlic eggs in a lifetime.
