This leaf-footed bug (family Coreidae) has succumbed to a attack by a parasitic fly. A fly in the family Tachinidae laid an egg on the bug's head (it is visible near the eye). The larval fly tunneled out of the bottom of the egg and into the body of its host, where it consumed it from the inside out. Finally, the maggot chewed out of the coreid and formed the puparium pictured, where it will undergo metamorphosis and emerge as an adult fly. Tachinid flies are 'parasitoids' because they are parasites that eventually kill their host.
