I Speak Opuntia, You Speak Progress is an installation and performance where the biopolitical is personal. Two female insect species; the Dactylopius coccus insect and Cactoblastis cactorum moth, tell their version of an official history of biocontrol. Both female species were involuntarily involved in a tale of species colonisation, species migration and political rhetoric masked as science, and played a vital role in the introduction of the Opuntia stricta cactus (Prickly Pear) to colonial Australia.
