Native to the harsh desert climate, these unpleasant creatures will burrow into any soft surface, including flesh, to avoid the sun. Their resemblance of a walking human ear lead to their name. Some slavers use these grubs as a restrainer for their captives, attaching a dormant extra ear to the forehead of their slave that can be remotely triggered.

Trivia[]
The description and use of these grubs is, barring their appearance as "ears", almost identical to the mind-enslaving "Ceti eels" found in the Star Trek movie Wrath of Khan. The eels buried their way into Human ears and latched to the brain internally, making the victim extremely susceptible to suggestion and more-or-less a slave. This may or may not be an intentional reference on the part of Frontier.
