The swarm can occupy another creature's space and vice versa, and the swarm can move through any opening large enough for a Tiny creature. The swarm can't regain Hit Points or gain Temporary Hit Points.

Actions

Ravenous Bites.

Melee Attack Roll: +4, reach 5 ft. Hit: 20 (4d8 + 2) Piercing damage, or 11 (2d8 + 2) Piercing damage if the swarm is Bloodied, and the target has the Poisoned condition for 1 minute as insects burrow inside it. The condition ends early if a spell or effect restores Hit Points to the target. While Poisoned, the target takes 4 (1d8) Piercing damage at the start of each of its turns. A creature reduced to 0 Hit Points by this damage dies.
