Clytocerus americanus is a species of moth fly belonging to the family Psychodidae.

The larvae have two prominent, horn-like projections situated in front and to the side of their head.

[2] The female terminalia consists of a bilobed subgenital plate the posterior margin of which is broadly V-shaped.

Their diet mainly consists of fungal mycelia and various microorganisms which inhabit wet to moist environments.

They spend much of their time resting on vegetation in perpetually moist or marginal habitats, such as woodland streams or springs.
