These birds are 12 cm long and weigh 8 g.
The mottle-cheeked tyrannulet is mostly found in moist, tropical mountain forests, but also in tropical moist forest at lower altitudes and temperate forests. They are present at altitudes of 1.000-2.300 m.
They feed on various insects and possibly also other small invertebrates.
Mottle-cheeked tyrannulets nest in a closed pouch-like nest with a circular entrance. There the female lays 3 eggs which are incubated for 18 days. There is no information regarding the length of the fledgling period.

This species has a very large breeding range and is described as fairly common. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
