Jack jumpers often hunt for spiders, and will sometimes follow their prey for a short distance, usually with small insects and small arthropods.[8] Jack jumper ants, alongside M. simillima, have been given frozen houseflies (Musca domestica) and blowflies (Calliphoridae) as food under testing conditions.[63] The ant has been observed to run and leap energetically at flies when they land, particularly on Acacia shrubs, plants or trees.[64] Jack jumpers and other Myrmecia ants prey on insects such as cockroaches and crickets.[65]
