With its mark sucessfully ensnared, the bug let go of the person's leg and took hold of his arms. Unless the person was paticularly strong, the bug wouldn't have much trouble subdueing him. While moving down the tunnel, the bug delivered a bite to the man's neck, sinking its four fangs into him, injecting a large dose of two different types of neurotoxins, garuanteeing death within the next minute.
Once the man died, the bug pulled him back to where it had began digging the tunnel. There, it rummaged through the man's pockets, removing what ever he might be carrying on his person and laying it down. After this, the bug ate the man, clothing and glob of glue included. Once consumed, the bug not only had stored a new amount of biomass, but also completely assimilated its victims memories. Whatever he knew, so to now did the bug.
Going through the memories, the bug went over what its victim knew about the bounty shop.
