 In Australia, the genus "Platybrachys" associates with "Eucalyptus" trees, while the genera "Olonia" and "Dardus" associate with "Acacia".Each eurybrachid female is likely to have an adult lifespan of some months, during which she lays several clutches of eggs.Females of many species deposit the eggs in clusters on bark or the undersides of leaves, placed in a fingerprint sized patch of white waxy material, covered by a white capsule that protects them from many predators.
