Lasius americanus, or woodland fuzzy ant, is a species of ant in the subfamily Formicinae.

[1] Lasius americanus workers are often a shade of dusty brown that have lighter semi-translucent legs.

Antennae do not have any erect setae (stiff hair like structures), and propodeum and back legs typically have very few near their base.

[2] Woodland fuzzy ants are typically found in North America, most predominantly in southern Canada and the eastern United States.

[1] They are most commonly found in temperate forests and woodlands, usually under rotting wood or in trees.
