Twist Fly and Twist Worm

The insect is depicted in both its pupa stage and adult stage. In the adult stage it has wings and can fly. It usually flies a great distance from it's spawning point, searching for a freshly killed corpse. Once found it drills the cylindrical ovipositor located on its posterior into the corpse and unloads a large amount of eggs into the deceased animal. These eggs hatch within a few minutes of release, where upon the Larva burrows deeper into the corpse, spreading in all directions. It only takes a few hours for the pupa to mature into the larva state, most commonly referred to as a Twist maggot, named for the way in which the larva twists and squirms in order to gain momentum through the tissues of its host. The pupa will fast for hours to days depending on the size of the animal present, and it will only enter it's cocoon stage when it sense final putrefaction of the tissues surrounding it. It creates a cocoon of rotted flesh around it's body, using the small hooks arranged along it's underbelly to maneuver flesh around it's form. Within twelve hours the adult fly has been formed and will release itself, searching out a new host body for the propagation of the species. It has no need for sexual reproduction, and all adult forms are born carrying egg sacks produced via self fertilization during the cocoon stage.

In very rare cases, twist fly's have been known to land on living creatures and inject their larva into the host. This will cause the eventual exceedingly painful expiration of the host organism, as the larva begin burrowing into the creatures flesh, seeking out the freshest morsel they can to grow faster.

The horn on the adult twist fly has been observed as a tool during fights for dominance of corpses. Many twist flies may gather over the same corpse and a fight will usually ensue, with only the strongest members of the race surviving. So far their has been no co-operative behavior noticed, nor any sense of a "hive" mind mentality.
