Phyllomorpha laciniata (the golden egg bug) is a species of coreid bug, and one of only two members of the genus Phyllomorpha.

They are specific to the host plant Paronychia argentea.

[1] It is noted for its habit of laying its eggs on other members of its species, who act as mobile nests (oviposition substrate).

These co-opted egg carriers provide more protection for the eggs than laying them at static locations on plant leaves or stems.

[4] This species was formally described by Charles Joseph de Villers in 1789, under the name Cimex laciniatus.
