Flyby: The moth doesn't provoke opportunity attacks when it flies out of an enemy's reach

Keen Sight: The Moth has advantage on Wisdom (Perception) checks that rely on sight.

Moonlight Shadow (1 / day): As a bonus action the Moth flaps its wings releasing luminescent dust forward in a 20-foot cone. Creatures in this area make a Dex Save (DC 15) or are coated in the dust causing them to glow a pale blue for one minute. For the duration, affected objects and creatures shed dim light in a 10-foot radius. Any attack roll against an affected creature or object has advantage if the attacker can see it. The creature or object can't benefit from being invisible.  

Wings. The moth creates a gust of wind with its wings. Creatures in front of the moth in a 20-foot cone must make a Str save (DC 13) or be pushed 10 feet away from the moth. 

Proboscis. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 12 (2d8 + 4) piercing damage. In moonlight this attack has advantage.
