The upperside of the tail is bluish green and underside slate gray with fine white bars.

[3] The lattice-tailed trogon's diet is mostly fruits and large insects but also occasionally includes small frogs and lizards.

It nests in a cavity excavated in a rotten tree or snag and sometimes an arboreal termitarium, usually between 5 and 8 m (16 and 26 ft) above ground.

The lattice-tailed trogon's song is a "rapid series of c.15 loud, resonant clucking 'kwa' notes rising in pitch and volume to a crescendo in [the] middle, then becoming faster, lower and softer".

[3] The IUCN has assessed the lattice-tailed trogon as being of Least Concern, though it has a restricted range and its unquantified population is believed to be decreasing.
