Beeblezug (5e Creature)
From D&D Wiki
Small undead, unaligned
Maggot Vomit. Ranged Weapon Attack: +6 to hit, range 20/60 ft., one target. Hit: 14 (5d4 + 2) piercing damage, and the target must succeed on a DC 15 Constitution saving throw or take 3 (1d6) damage and become infested with maggots. The target makes this save at the start of each of its turns, taking damage every time it fails. After the target completes a long rest, they or someone else can end this infection with a successful DC 18 Wisdom (Medicine) check; otherwise, it can only be cured with lesser restoration or a similar spell.
An unusual form of zombie known for the symbiotic insects it employs as an external digestive system. A beeblezug carries a specialized breed of carrion fly, which live in the creatures intestines and may hatch up to several thousand maggots per day. Foregoing any pupal or imago stage, the large, voracious insect larvae function as the beeblezug's primary feeding and defensive mechanism, regurgitated by the toothless creature to break down organic matter into a more palatable slop and reingested as it feeds. Beeblezug are shy, reclusive creatures that prefer to scavenge kills from larger monsters or harmlessly graze on the non-vital tissues of zombies, but may reflexively regurgitate in the literal face of danger. "Tickled" by the excited writhing of its symbionts, a beeblezug's level of hunger is easily deduced from its degree of squirming, shuddering and "dancing" as it approaches the scent of a pungent meal. A beeblezug's regurgitation is preceded by a loud and extended "snorting."
