[1] Adult P. citri have light grey forewings with dark grey/black spots and greyish brown hindwings and body.

[2] But an examination of genital structures is necessary to correctly identify P. citri from other species of the Prays genus.

[2] Adult female P. citri release a pheromone, identified as (Z)-7-tetradecenal,[3] to attract male moths.

[4] After this, the larvae pupate and form a cocoon on the Citrus tree, and after about 6 days, a moth will emerge.

[4] The preferred host plant of this P. citri is key (sweet) lime (Citrus aurantifolia).

[8] Less susceptible host plants include grapefruit, sour orange, and mandarin.

[2] P. citri have a couple natural enemies including a pathogens, two parasites (Ageniaspis fuscicollis and Nemorilla maculosa), and a predator (Metaseiulus occidentalis).

[4] P. citri is a significant pest to Citrus, reducing crop yields by up to 30%-40%, and are therefore economically costly.

[2] When the larvae emerge from their egg, they feed on the flower causing significant loss in fruit production.

In field studies with P. citri, this pheromone can be applied to a sticky trap to capture males.
