It has long shiny green cheek tufts with large blackish blue spots at the ends and a rufous patch with a white dot near the eye.

Its tail is grayish; the feathers have a wide purplish bronzy band near the end and the outermost pair have white tips.

Subspecies L. p. duidae is similar to the nominate but its black crown line and the rufous patch on the cheek are smaller.

The species inhabits the interior, clearings, and edges of rainforest and cloud forest at elevations between 500 and 2,000 m (1,600 and 6,600 ft).

[6] The peacock coquette is thought to be mainly sedentary but appears to make migratory or nomadic movements in Sierra de Lema.

[6] The peacock coquette's vocalizations have not been described, and as of February 2022 no recordings are available at Xeno-canto or Cornell University's Macaulay Library.
