Jumping on top of the jeep, the glue-covered ranger painted his rifle at the bug, a bit shakily, the glue covering his face hampering his ability to breathe, and the noxious fumes weren't helping in that regard. Seeing the rifle pointed at it, the bug swept its tail at the ranger as he aimed, knocking him out of the jeep. The ranger landed on his back and tumbled a few times before coming to a halt.
While the bug advanced a few paces after knocking the ranger out of the jeep, the ranger that had taken over the steering picked up his rifle and pointed it at the bug over his shoulder, largely blindly taking a shot at it. The shot did hit the bug, wizzing past the side of the abdomen, taking out a piece of its exoskeleton. While uttering a pain, shrill shriek and loosing its grip, the bug managed to regain its grip after sliding a little before falling off of the jeep. Making snorting noises, the bug advanced over the jeep again, towards the ranger who was now struggling between keeping the jeep under control and loading the next round into his rifle. This gave the bug all the time it needed to approach the ranger and lunge its maw at him. The mandibles closing in around his head, the ranger uttered a muffled scream while the bug applied pressure, before a crack sounded, followed by a wet thumping noise. Lifting its head, the bug swallowed the top half of the ranger's skull it had bitten, leaving what was left behind to topple over and spill grey matter.
After swallowing the bite, the bug leapt up and flapped its wings to safely touch down on the ground, shrieking a little as the bullet wound pained it. While the jeep spun out of control over the bumpy dirt road and flipped onto its side, the bug spun up a patch of the same material it used for its cocoons, and applied this over the entry and exit holes of the bullet wound, then limped over to the ranger it had thrown out of the jeep, its tail dragging behind it.
Reaching the ranger, and began eating him, hurriedly biting the body into smaller chunks and gobbling them down. When finished, the bug moved off the dirt road, back into the grasses, where it huriedly dug a small tunnel. Crawling inside, the bug cocooned itself.
