Fond of cool, damp conditions where it can feed on mildew, fungi, cobwebs and gastropod trails, this drifting, luminous fectoid prefers to be left alone in abandoned buildings, bat caves, bogs or hollow trees. It will usually attempt to drive intruders from its territory with its subsonic howl, which induces uncontrollable fear and panic. It glows brilliantly under the full moon, and has been known to imitate lantern light in an attempt to confuse interlopers.
