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.[1][2] While Phyllomorpha laciniata females can and do lay eggs on their host plant, the availability of suitable egg carriers seems to stimulate the deposition of mature eggs.[3] In the golden egg bug, all females carry other female’s eggs, and most males carry eggs they have not fertilized.[4]
Taxonomy
This species was formally described by Charles Joseph de Villers in 1789, under the name Cimex laciniatus.[5]
