Adults are on wing year-round.

The larvae have been recorded feeding on Psidium species (including Psidium guajava), Feijoa sellowiana, Macadamia integrifolia, Eriobotyra japonica, Prunus domestica, Prunus persicae, Pyrus pyrifolia, Citrus species (including Citrus unshiu and Citrus limon), Cassine australis and Schizomeria ovata. They bore into the fruits of their host plants. First to third or fourth instar larvae are found inside ripening fruit while the fruit is still on the tree. In fruit such as loquat, macadamia and peach, larvae are found feeding inside the kernel. Larvae leave the fruit through an exit hole to pupate when the fruit has fallen to the ground.
