Rimewing

Antennae. The giant moth has advantage on Wisdom (Perception) checks that rely on smell.

Proboscis. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) piercing damage.

Frosted Wings (1/Day). A 20-foot radius cloud of colorful ice crystals extends from the rimewing. Each creature in that area must succeed on a DC 10 Wisdom saving throw or be charmed by the rimewing for 1 minute. While charmed by the rimewing, a creature is incapacitated and must move up to its speed toward the rimewing at the start of its turn, stopping when it is 5 feet away. A charmed creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
