Human: Produce a detailed written description of a dark scene outside a wilderness forest with a branch, white grubs, and insect larvae. Assistant: 
The limb groans under the unaccustomed weight of visitors. Something has stripped the branch of its bark, maybe the insect larvae of a wood-boring beetle that now infest the creaking limb, making every step both distasteful and dangerous. A plump, white grub inches its way to a richer feeding spot, and disappears into the limb.
