Ear seeker

In the Dungeons and Dragons fantasy role-playing game, the Ear seeker is an insect-like creature. They resemble tiny worms with wings. The creatures are named because they need warm places to lay eggs, and their favorite of such warm places are the ears of other, larger creatures, most commonly humans. The eggs burrow into the ear, severely damaging the tissue and likely defeaning the victim, and when they hatch, they go into the brain and partly consume it, and the victim has a 90% chance of dying. The creatures then emerge from the ear as fully grown adults, and go off to lay eggs of their own to start the process once more.

Ear seekers cannot speak.

They are regarded as neutral in alignment, despite distinctly evil habits.
