Maskfly

Maskflies are enemies in Hollow Knight. They are docile flying creatures who travel in flocks, fleeing from anything they perceive as a threat.

Behaviour and Tactics
They sit in a flock until disturbed, upon which they take off and quickly fly away, even before the Knight gets into Nail range. They will also fly away if any other enemy gets too close.

To kill them, dash forward to get them faster or stay out of range and use the Vengeful Spirit spell. It is also possible to kill them easily using the Crystal Heart, as the Knight will not take contact damage.

Location
Maskflies can be found in groups in Greenpath and Queen's Gardens.
